Cillian Murphy is an actor who has played roles in films such as 28 Days Later and Batman Begins. He is an Atheist.
After the filming of Sunshine, Cillian Murphy, in an interview with the UK Daily Record noted that working on the film "...got me thinking about life and religion, science vs religion and all that. I was verging on being an agnostic and this film confirmed any of the atheistic beliefs I had. Not just because I spent time with these guys--they just confirmed what I'd always suspected. For me, the film ultimately is a battle between science and religion, or science instead of fundamentalism."
