How does a total cinematic disaster come about? We're talking one of those movies that is just so awful you can hardly believe it. I think a lot of bad movies, like Tim Burton's Planet of the Apes, for example, come about by accident. Burton probably started it with the best intentions and then realized at some point -- after it was too late -- that he had a stinker on his hands. So he kind of shut down his brain and continued on autopilot. As a defense mechanism, he probably tried not to think about it too much. But that kind of filmmaking merely results in a bad, dull film. No, I think to make a true disaster you have to have your head in the game. You have to be enthusiastic and committed, like John Travolta on Battlefield Earth.
I would suspect that Kevin Smith did the same on Cop Out. Even if he started to smell something bad during the production of his latest film, he probably kept a big smile on his face and kept on having fun. He might even have been making fun of his own movie as it went along on its merry path to hell. The result is awful, but whether or not it's a true disaster remains to be seen. (There were about three minutes at the beginning where I had my hopes up for a good movie.) However, I'm sure my jaw was hanging on the floor far more often than it was engaged in the act of laughing.
