Here's how Gervais -- with his typical sense of humor -- described his celestial character in a blog post on his website: "But he's a slightly different God to the one you may have seen in 'Bruce Almighty' and other Hollywood films. He's an arrogant, wisecracking son of a bitch, who thinks he's the best thing since sliced bread. (So another stretch for me as an actor then.)"

Just because the main character is an atheist, don't expect God to smite him.

"He also loves welcoming atheists to heaven with a smug grin on his face," Gervais wrote. "He likes atheists deep down though. Or rather he likes good atheists. He admires the fact that they were moral people even though they didn't believe they would ever be rewarded with everlasting life."
