Corrected entry: When Ricky Gervais discovers he can lie, and is in the bar trying to explain this to the bartender and his friend, his beer is 3/4 full. By the end of the scene the beer is almost empty, and based on the speed of the conversation, he did not have time to drink the beer between shots of him. (00:23:20 - 00:24:35)
Corrected entry: Since religion is an entirely new concept, why is the minister at the wedding wearing a Christian cross? Everything else about the church reflects on Mark's teachings.
Corrected entry: In wide shots of the city there are several religious buildings in the shot.
Corrected entry: Wouldn't Mark's revelations about the afterlife lead to mass suicides? Unless I missed the part where Mark stated that suicide is against the "man-in-the-sky's" rules, this is a major plot hole that cannot be overlooked. Early in the movie Frank even mentions different suicide attempts. Why didn't Gervais and Robinson include a suicide rule in the screenplay? It would have been both logical and simple.
Corrected entry: A major part of the movie is that religion is a lie that this world never had. Why then do they use the Gregorian calender? Mark writes movies about the 13th century; 13 centuries after what? If no one has ever believed in God or any god, then the life of Jesus becomes historically insignificant. Certainly not important enough to use the year of his birth as the starting point of the calender.
Corrected entry: If lying has not been invented why does the casino cheat, which is implied in the movie, and even though they are up front about it cheating is a form of lying.
