This is a very funny movie. And i like it a lot. I have been laughing for the whole movie. And there are lots of superstars, such as Tom Cruise and Robert Downey, who are both my favorite actors.
My favorite character is Jeff Portnoy, the fat guy. I think it is disgust that makes him interesting. He is famous for farting in a movie performing all the characters on his own. It is really disgusting that he farts so much, it is interesting, though. It makes people laugh cause he is so good at it. Also, he does a lot of stupid things such as not following the team and running for heroins, which make other characters into a bad situation.
I think the most interesting moment is that when they found out that Alpa Chino is a gay. Because it's so funny that he changed the name of the man he likes, Lance, into Nance to pretend he is not a gay, Especially when Jeff Portnoy said he would literally do some dirty thing for him if Alpa Chino released him.
Otherwise, this movie also tells us that actor is such a unsecured job, that actors' lives are not easy. It shows us how people fight for being in a movie. They will do something they are unwilling to do only if they can be on the scene.
