Scary Movie 4 is an interlinked series of parodies, mostly of horror movies (War of the Worlds, The Grudge, The Village, Saw ) with Cinderella Man and (a very up-todate touch) Brokeback Mountain thrown in. It's vulgar, fast-moving, ingeniously integrated and much better than the preceding Scary Movie films, largely because the director this time is David Zucker, who (with his brother and Jim Abrahams ) virtually invented this sort of picture with Airplane! 25 years ago. The most daring touch is Leslie Nielsen's Bush-like President, first seen being given the news of an alien invasion while sitting in a nursery school classroom, more interested in a kid's story than the approaching apocalypse.
