Hinting at the lack of care given the film, a number of the scenes in the trailer don't appear in the film; conf irming it, a number of the scenes reprised in a late-in-t he-film flashback aren't even "prised" in the movie befo rehand. But the key problem is that the comedy seem s to have been more typed than written, in that the poin t of such parody, which is to (1) borrow characters from other works and then (2) do something funny with them , has pretty much been ignored, at least as far as (2) goes. As a date movie, this is one made for not viewing from the backseat at a drive-in. Starring Alyson Hannigan and Adam Campbell. Directed by Aaron Seltzer. Written by Jason Friedberg and Aaron Seltzer. Produced by Paul Schiff and Jason Friedberg. A Fox release. Comedy. Rated PG-13 for continuous crude and sexual humor, including language. Running time: 82 min.
