MICHAEL PEŅA (left center) and DEREK LUKE (right center) in 'LIONS FOR LAMBS'

Pena readily admits he's not "big on religion" but he happily took a moment with Luke to get into character for war scenes in the Robert Redford movie.

He explains, "He asked me to pray before every scene. I prayed with him and it was interesting and it helped us a little bit. It made some scenes really count for something.

"Prayer was not something I normally did and here I am having a conversation with God in front of somebody I've just met. It kind of puts you out there.

"You're raw as can be and you're asking God for guidance before the scene."
