The lapsed Catholic admits he enjoyed picking up The Bible and chatting to men of the cloth as he researched his role - Liotta's first as a clergyman.

The Goodfellas star says, ""I was brought up Catholic so I went to church but I never played a preacher before. I read The Bible a lot and I haven't done that in a while, so that was interesting.

""I would go to a Baptist church or a Catholic or a Methodist (church) and watch sermons and talk to preachers after they were done. It was really interesting. They each have a different vibe to them.""
