Based on what's shown, it looks like our Airplane friends are using the film The War of the Worlds as a main storyline, only it seems the aliens here take over the world using an iPod (I had to snicker at that one). Leslie Nielsen will play a moronic President of the United States (Little late on this joke?) who would rather wait to see how a children's book turns out than save the planet; an obvious poke at George Bush's initial reaction to 9/11.
Some of the other films on the chopping block include The Village, The Grudge and SAW (featuring a scene between Shaquille O'Neil and Dr. Phil). Oh, and there's also a spoof of the Tom Cruise jumping on Oprah's couch like a buffoon thrown in as an extra bonus. Part of me is happy to see some new blood (David Zucker and Jim Abrahams) injected into the franchise, however, their jokes don't seem to have that special zing we've seen previously. Scary Movie 4 hits theaters on April 14th.
UPDATE: Yahoo has added the real Scary Movie 4 trailer, complete with actual music and everything. Check it out here.
