Dane DeHaan felt 'out of breath' filming long action sequence in Valerian

Dane DeHaan was amazed to see the finished version of the movie.

Dane DeHaan felt lucky he "didn't puke" after filming an extended action sequence around 25 times for Valerian and the City of Thousand Planets.

The Amazing Spider-Man 2 actor trained extensively so he could take on the physically demanding role of federal space agent Valerian in Luc Besson's latest sci-fi flick, and that came in handy when he had to film an elaborate action sequence in one continuous take countless times.

"There's one shot in the Big Market sequence that's like a 45-second shot where they set up an obstacle course I had to run around," he told WENN at the movie's premiere in London. "I had to run this obstacle course, it was like a minute long, and just plough through people and go up stairs and down and jump and somersault.

"I was pretty out of breath after the first one but we had to do (it) about 25 times so luckily, I trained pretty hard so I didn't puke that day."

The fictional Big Market is a multi-dimensional shopping mall that customers can access by wearing virtual reality gloves and glasses and the sequence features shots of action happening both inside that world and outside.

Luc admitted the Big Market was the hardest sequence to film because of the two dimensions.

"The most difficult was the Big Market at the beginning because there's the two worlds in the same world and it was a nightmare to do. It took us almost five weeks to do just this scene and that was a tough one," he said, adding it "looks easy when you watch it."

The Fifth Element director has been wanting to make an adaptation of French comic Valerian and Laureline for years but he waited for technology to catch up with his vision and to have enough “experience and the guts” to do it.

Dane, who stars alongside Cara Delevingne as Laureline, filmed most of the movie against green screen and was blown away by the world Luc created when he saw the finished product.

"There's just so many different worlds and so many different aliens, it's just amazing to see what was in that guy's head the whole time we were shooting," he said.

Valerian and the City of a Thousand Planets is in cinemas now.
