Ben Affleck in talks to star in The Accountant sequel

Director Gavin O'Connor is also in negotiations to helm the film.

Ben Affleck is in talks to reprise his role in The Accountant sequel.

Director Gavin O'Connor and screenwriter Bill Dubuque are also in negotiations to return, alongside producers Lynette Howell Taylor and Mark Williams, according to Deadline.com. Jon Bernthal, who played Affleck's brother in the clever 2016 action movie, will also reportedly be back.

Ben played a socially awkward mathematics genius who hides his links to international gangs in the film, which also featured Anna Kendrick.

The 44-year-old star previously revealed the film's complex take on parenting is what drew him to the role - his character is the product of a broken home and an abusive, controlling father.

"Here's a guy out of love and compassion and fear for his son, actually ends up kind of brutalising him and abusing him and it's a really interesting look at what's the appropriate way to channel the intense emotions we have as parents, it's not easy," he told People magazine.

Ben, whose character suffers from Asperger's syndrome, also enjoyed the research he had to do for the role.

"On the one hand there was a lot of fight rehearsals, training," he said. "A lot of those fights I wasn't wearing a mask (like when I played Batman)..., but what I really cared about was getting the autism aspect of it right.

"We watched a lot of movies, read a lot of books, watched podcasts and then met with specialist and teachers and finally got hooked up with a bunch of guys in my age range who are on the (autism) spectrum, and they were really helpful and really self aware and really funny and really wanted to make the movie great with this autistic protagonist. That was the best part of the experience for me."
