[Bradley Cooper] and J.J. go way back because he was on Alias. And we needed to cast a very small role. And he said, ‘I wonder if Bradley would do it.’ He reached out and he was really stoked to help us out.

10 Cloverfield Lane is a film that’s shrouded in secrecy. But with its release date now less than a week away, more and more information regarding the mysterious project is being released. And one of the biggest revelations is that Bradley Cooper has a role in the film.Obviously, since viewers have little to no information regarding 10 Cloverfield Lane, I won’t go into specifics about Bradley Cooper’s mystery role, so as to keep you all spoiler-free for the film's premiere this week. However, what I will say is that when I sat down with 10 Cloverfield Lane’s director Dan Trachtenberg on Sunday to discuss the film, he revealed exactly how Bradley Cooper became involved. As it turns out, we have J.J. Abrams to thank for Cooper's participation, as Trachtenberg explained:As Dan Trachtenberg pointed out, Bradley Cooper and J.J. Abrams previously collaborated on the ABC spy show Alias, which was created by the Star Wars: The Force Awakens co-writer and director. So if J.J. Abrams , whose company Bad Robot produced 10 Cloverfield Lane , could turn to Bradley Cooper and ask The Hangover and American Sniper actor to appear in the sci-fi thriller in "a very small role," the pair are clearly still good pals. Who knows, maybe even Bradley Cooper has a cheeky cameo in Star Wars: The Force Awakens that no one has found out about yet. 10 Cloverfield Lane has been described as a "blood relative" to 2008’s Cloverfield. Written by Josh Campbell, Matt Stuecken, and Damian Chazelle (Whiplash); the film stars Mary Elizabeth Winstead as Michelle, who after surviving a car accident wakes up in an underground cellar. She was taken there by John Goodman’s Howard Stambler, and, alongside the bunker's other inhabitant, played by John Gallagher Jr, she is soon informed that the Earth’s surface has been left uninhabitable by a chemical attack. But can she trust Howard, or his version of events? And what is actually lurking outside? The only clues we have are from trailers such as the one included below:
