As we've previously discovered, film stars a egotistical bunch, and with people around to bow to their every whim, they can get a bit carried away.
When major Hollywood players work on the film, they are treated to certain freebies and goodies, but sometimes they reel off a list of demands that are bizarre, self-centred and ridiculous.
13. Uma Thurman demands prop wigs at 50% off (if she wants them)
When the Kill Bill star signed on for book adaptation Eloise in Paris, she had a very specific set of demands written into her contract.
Offbeat website The Smoking Gun got their mitts on a copy of the contract and pulled out some of Uma's more unusual clauses (see the full document here).
Employing virtually-complete creative control, Uma's contract deemed her veto power over the film's screenplay, director and co-stars.
Also, despite bagging $4.5m for the movie, Uma is always on the hunt for a bargain, and she had it written into her contract that she would have the option to buy wardrobe items and wigs created for her at 50 per cent off.
Uma Thurman fans, if you were scratching your head and wondering why you'd never heard of Eloise in Paris, it's because it was never made, nor was much progress made on putting the film whatsoever. As a result of this, Uma settled on a $6m compensation lawsuit against Handmade Films.
12. Orson Welles demands a fur-lined coat, then steals it
While filming adventure film The Black Rose in 1952, the legendary film star insisted that his character Bayan wore a coat lined with mink.
Despite the cost, the producers gave in and got Welles the coat that he had requested, which was unusual as the mink lining of the coat was never shown on screen - perhaps Welles felt it would make him act better.
The producers discovered that once the film had wrapped, the coat had disappeared; only to turn up again on Orson Welles in his 1952 adaptation of Shakespeare's Othello, this time with the fur lining exposed.
11. George Clooney demands a hot tub, beach hut and basketball court built in Surrey
While filming 2013 space epic Gravity, at Shepperton Studios in Surrey, George Clooney wanted to forget that he was residing within the M25, but how would he do that?
Next to his trailer, the Cloon (as we're calling him) had a custom-made beach hut complete with hot tub, private landscaped garden and basketball court built next to his trailer.
The star demanded the whole set-up be built next to his trailer at a cost of £100,000, while he picked up a reported $20m plus a share of revenue.
We're sure Clooney's set up was the envy of all Gravity's cast and crew that had to stand around in a bleak Portakabin, drinking tea out of polystyrene cups.
10. Paris Hilton demands live lobsters on standby while doing a cameo
You probably don't remember Paris Hilton 'starring' in the cop comedy The Other Guys with Will Ferrell and Mark Wahlberg.
That would be understandable, as the scene in question in which Paris plays herself in a cameo and is saved from a helicopter crash, was cut from the final film.
Paris' team handed the movies' producers a three-page list of what she wanted on her rider, which included fresh lobsters to be prepared fresh when she was ready and a bottle of Grey Goose vodka - all for one day on the set.
9. Jack Nicholson demands a dildo and cocaine for his character
While working with Martin Scorsese on The Departed, Jack Nicholson came up with a couple of his own interesting ideas for his Boston mob boss character Frank Costello.
"I thought it would be more frightening if my character had a sexual component," Nicholson explained in an interview with Rolling Stone.
"So I called Marty up and said, 'Look, I just thought of what would be an interesting scene of [my character] having wild sex. And in this scene with two girls, one of the girls is wearing a strap-on'"
As well as that, he also wanted to dust the backside of one of the actresses with cocaine, to which Scorsese thought would work, so went ahead with the idea.
Fortunately, Scorsese’s film-making ability resulted in a scene that was probably way crazier in Nicholson's head that ended up in the film.
8. Bruce Willis demands $1 Million for each day of shooting The Expendables 3
With the all-star action cast The Expendables on its third incarnation, the ante was constantly being upped as new cast members (and explosions) were added to the film.
But Bruce Willis, who'd previously featured in the first two, wanted his share of the pie, if the pie was money, and if 'his share' was 'ridiculous amounts for not doing much work'.
According to a source, Willis was offered $3 million for FOUR DAYS work in Bulgaria for his appearance.
The Die Hard star refused, "he said he'd drop out unless he got $4 million. A million dollars a day."
Sly Stallone, writer of all three Expendables films, along with the film's producers said no and dropped Willis from the project altogether, drafting in Harrison Ford 72 hours later.
Stallone then tweeted:
WILLIS OUT... HARRISON FORD IN !!!! GREAT NEWS !!!!! Been waiting years for this!!!!— Sylvester Stallone (@TheSlyStallone) August 6, 2013
Followed up with:
GREEDY AND LAZY ...... A SURE FORMULA FOR CAREER FAILURE— Sylvester Stallone (@TheSlyStallone) August 6, 2013
Twitter once again proved itself the go-to place for passive-aggressive messages.
7. Quvenzhané Wallis demands to be billed above Cameron Diaz
Quvenzhané Wallis was cast alongside Jamie Foxx and Cameron Diaz in the Annie remake as the titular orphan at the age of 10.
Already boasting a Best Actress Oscar nomination for her performance in Beasts of the Southern Wild, she had a stellar reputation and a bit of an ego to boot.
Quvenzhané (pronounced kwuh-VEN-zhuh-nay) was offered $1.5 million to play Annie, but the young actress wasn't just after the money - Wallis' contract stated that her name would appear no lower than second position in the title credits.
While she was playing Annie in the film Annie, it would mean that Hollywood heavyweights Jamie Foxx or Cameron Diaz would have to drop below the young star.
As well as that, Q's contract demanded 'veto power on any bloopers before they're released', as well as her trailer being kitted out with unlimited Wi-Fi, despite the star's Twitter account being managed by her parents.
As she's just starting out in the film business, imagine what her demands will be like once she is an established Hollywood (hard-to-pronounce) name.
6. Steve McQueen demands to be slightly higher on the poster than Paul Newman
When fierce rivals Steve McQueen and Paul Newman starred together on 1974's The Towering Inferno, there were intense arguments over who should get top billing.
McQueen, who started the rivalry, demanded that they each have the same salary and exactly the same amount of lines, while the pair argued who should get top billing.
Eventually producers settled for a quirky compromise for the poster, McQueen's name is first, but Newman's name, while second, is slightly higher up.
Also the picture of McQueen is on the left, but Newman's picture is again slightly higher up. This coined the term 'diagonal billing'.
5. Will Smith demands a double-decker $9,000-a-week trailer
While filming Men in Black III, Will Smith let his reputation as one of Hollywood’s nicest guys fall, as he started dropping demands all over the place.
The star ordered a set to be torn down because "it wasn't right" as well as providing a list of 'must hires' list, including many of his own entourage.
The biggest issue concerning the filming on the streets of New York was Smith's hulking double decker mobile home which cost the filmmakers $9,000-a-week for the star to reside in.
New York residents complained about the 53-foot mega-trailer stank the neighbourhood up with exhaust fumes and was forced to be moved.
4. Gary Busey demands a 'realistic' heaven set is built
When Gary Busey was set to star in the terrible 2003 family comedy Quigley, where he plays a rich idiot who dies, but instead of going to heaven, is reincarnated as a dog to right his wrongs.
Gary Busey has first-hand experience in entering the Pearly Gates after crashing his motorcycle while not wearing a helmet and 'dying' on the operating table during his subsequent neurosurgery.
When Quigley's 'heaven' set ready, Busey came in and threw a strop that it looked nothing like heaven, and of course, he had actually been to heaven.
Busey's co-star, Curtis Armstrong, was recounted the story to FilmDrunk:
"He showed up on a set made to look like Heaven, and he looked around and said, “I can’t play this scene.” Armstrong explained.
"They were three days behind at this point, but Busey said: “It’s nothing like this. I’ve been to Heaven and it doesn’t look like this. That sofa’s all wrong. That mirror is ridiculous. They don’t even have mirrors!” It was ridiculous. He was completely nuts about the design of Heaven."
So filmmakers, if you're going to do a scene in heaven, have Gary Busey on hand to make it an authentic portrayal.
3. Jim Carrey demands his private jet gets a cameo
When the rubber-faced comedy star shelled out $59 million on a Gulfstream V private jet, he wanted to get his money's worth, even when it wasn't flying him around the globe.
Carrey, who laughed off a rumour that he demanded a special chef just to whip up meals for his pet iguana, has actually made some baffling demands that made the iguana chef demand believable.
The Eternal Sunshine of the Spotless Mind star is so proud of his jet, that he has told studio bosses that if any film that he appears in shows planes, in any context, the footage must also include shots of his own jet.
Perhaps it is to make sure it isn't left to gather dust in an airport hangar while he is grounded working on a film.
Keeping with the flying theme...
2. Angelina Jolie demands for the movie studio to pay for Brad's flying lessons
Hollywood's biggest power couple (and most-diverse brood) look out for each other even while at work.
According to an undisclosed movie studio, as part of her contract, Jolie requested that Brad Pitt - who had nothing to do with the alleged film - have flying lessons.
Jolie, who owns a pilot licence of her own, wanted her hubby to take to the skies, and saw a crafty opportunity to get it all paid for without having to shell out herself.
1 .Tom Cruise demands over 50 custom-made thongs
If widespread rumour is to be believed, Tom Cruise is a weird dude, and it wasn't helped when a source close to the star revealed that he wears a thong when shooting action scenes.
Star of the Mission: Impossible series allegedly demands thongs that are made from stretchy and soft material, and they allow him to be unrestricted when he performs action sequences and stunts.
The insider told the Daily Star: “There aren’t many movies where you don’t see Tom rolling around on the ground or, doing a back flip off the side of a skyscraper.
"Over the years it’s taken its toll and he had his wardrobe department rustle him up a comfy thong.”
The source went on to say “He was embarrassed at first but he sees it as a way of improving his flexibility as he gets older. He’s pretty insistent about having a new thong every time. We do have a laugh but he sees it as dedication to his craft.”
Cruise's love for doing his own stunts is widely publicised and his M:I stunts have seen him running down the world's tallest building, and hanging on to the side of a plane as it takes off.
Mission: Impossible costume designers and wardrobe staff were asked to amass over 50 thongs whenever he is on set - just think about that when you see him on screen performing a death-defying action set piece.
