I don't know if someone has already suggested this one, but I just watched it and it was really amazing. It's a movie called The Ledge, and for atheists and christians alike it is very thought provoking. It's message could be interpreted differently when seen through different eyes, but for me, it was trying to convey that atheists believe in things too, just not gods. It was just a mind blowing, well made film. Check it out. I watched it streaming online for free
