Why is making fun of 8 Mile briefly such a big deal when no one minds the many Matrix spoofs in the movies? And I guess you didn't get the TCM, Motel Hell, or The Others references, huh?
The Wayans Brothers are not funny. Well, I found Damon Wayans funny in some things he was in. Other than that, the Wayans have never made a good movie.
David Zucker made Airplane!, Top Secret!, and the first two Naked Gun movies, with writing credits to the third. That is an excellent list of spoof movies which made him a better candidate to make another spoof movie rather than the Wayans.
And damn, let's get some spoof actors in this too. My first two picks, Leslie Nielson of the Naked Gun trilogy (among other spoof movies) and Charlie Sheen of the Hot Shots! movies. And they're both in it.
I'm looking forward to Scary Movie 4.
