Denzel Washington and the cast of mystery thriller Flight hit the red carpet in London for the film's UK premiere.
The movie comes out here next month, and Washington's already been nominated for an Oscar for his performance.
He plays a top airline pilot who saves a plane from crashing.....but an investigation raises some troubling questions about what really happened on that flight.
"I mean, it's a complicated character, but you work on the flying part of it, he explained.
“I had the opportunity to work with flight simulators with Delta Airlines. You just play the part.
“The good thing about this movie is that it's really on the page, it's a very well written script, so it made my job easier.”
The film marks a comeback to live action cinema for award-winning Forest Gump director Robert Zemeckis.
