Ben Affleck will direct and star in 'Witness For The Prosecution'.
Ben Affleck
The 44-year-old actor and director is set to take on the adaptation of Agatha Christie's short story about a lawyer defending an accused murderer for Fox.
Ben will produce alongside Matt Damon, Jennifer Todd and the Agatha Christie estate.
Matt and Ben shot to fame with their 1997 movie 'Good Will Hunting', and while they are keen to write another script together, the 'Jason Bourne' actor recently admitted their "grown-up lives" get in the way.
And with Ben now working more as a director, Matt would also happily star in one of his films - but only if his pal stayed behind the camera.
He said: "I would love to write another script with Ben; I love Ben, I love his work, he's been my buddy for 35 years. The big issue is time for us. We have a company together so we work on a lot of projects together, but to try to carve out the time is really tough.
"I mean we both have a whole mess of kids now, and these other day jobs.
"He's directing all the time and I'm off working with these other directors. The thing about 'Good Will Hunting' is that we were unemployed and we weren't writing the script on a deadline either. Nobody was expecting it, so we were just these two idiots in our basement writing this thing, and now we have all of these pressures of the lives grown-ups have.
"So I would never say never because I would absolutely love to write with Ben again, and I'd love to collaborate with him on anything, he's brilliant. I'd love to be in one of his movies that he directs.
"The problem there is that he just keeps giving himself the best roles, so until he stops doing that and maybe just directs, none of us can really work with him."
It's unclear if Matt will take on a role in 'Witness For The Prosecution'.
