Adam Carolla's Theories.
2 good theories about how this movie got made:
1) They came up with the title first. Then came up with the movie based off that.
2) In order to get a major studio to make this, and give it a legit budget, they needed to A-list leads. First they went to Cage, and told him if he agreed they promise they could get someone else to co headline with him. He said maybe. Then they went to Travolta, and said Cage will do it if you do it. Then they go back to Cage and said Travolta will only do it if you do it.
