Film: Bruce Almighty.

The protagonist (Jim Carrey) loses his work, his wife (Jenifer Aniston) and he is very angry with his life. He has the opportunity to be God (Morgan Freeman) for one week.

He thinks this will be easy work. He discovers that this work is more difficult than he thought. Too many problems to organise, too many decisions. At the final he does not want to be God and wants to return to the life before. His life before is better.
