Homeland star Damian Lewis first left America because he found Hollywood to be ''bloated and corrupting''.
Speaking at a London TimesTalks event organised by the International New York Times, 43-year-old Lewis said: ''I just didn't feel I wanted to live in LA. There was still theatre that I wanted to do, there were a couple of big movies floating around.
''I ended up choosing a movie about aliens exploding out of people's bottoms - which might be a decision I take back - an adaptation of a Stephen King novel called Dreamcatcher.
''I actually ran away from LA slightly put off by that experience, not the film itself, but there seemed to be something bloated and something slightly corrupting about [Hollywood]. I couldn't quite put my finger on it at the time.''
Lewis further admitted that he didn't set out to be a well-known star, adding: ''In '93 when I came out [of drama school], acting was still very much a classical education, a training based on classics, theatre history and understanding of what our heritage was.
''I remember heading off to Amsterdam for New Year, standing on the prow of some ferry talking passionately about how we were going to be the next generation of theatre actor, shake the West End up and take the RSC by storm...
''We weren't all like that, Ewan McGregor was the year ahead of me, he just walked around the school saying, 'I wanna do movies.' I've no idea how that's gone for him!''
