Murphy, who heads up the annihilation of the sun in the Danny Boyle-directed movie, spent time with a number of scientists to prepare for the role--and ended up losing any belief in a bigger being.
He says, "I was agnostic before this film. Now I'm very much an atheist.
"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."
