James stars in the film along side Jonah Hill, while Brad is behind the scenes as a producer. And surprisingly, we learned, that this was the first time James and Brad met, and according to the 36-year old star, it was love at first sight!

In an interview with Rupert Goold, the movie's director, James revealed, "We fell in love last night, he's the coolest guy."

And despite only meeting at this year's Sundance, James had nothing to say but good things about Angelina Jolie's husband.

"He really kind of saw it through from script stage and post-production stage and was really helpful that way... But it was the first time I actually met him last night."

True Story features James Franco, Jonah Hill, Felicity Jones, Gretchen Mol, Betty Gilpin and John Sharian. It is based on the real-life memoir of American journalist Michael Finkel, who Jonah plays. James plays the role of Christian Longo, the man who killed his family and tried to hide under the journalist's identity. The film is set to be released on April 10, 2015.
