Immensely entertaining albeit somewhat trashy De Palma reworking of a few Hitchcock classics (Vertigo and Rear Window). Some of the Hitchcock references are quite obvious However, it's clear that this isn't a direct rip-off, but rather De Palma melding some of Hitchcock's themes and techniques into his own style. Either way, you have to admit that De Palma takes these themes to a disturbing level that is well beyond anything Hitchcock ever did whether this works for or against the movie is for the viewer to decide. The sleaziness and B-Movie feel is also something that may put off some viewers but others may enjoy. Some truly excellent scenes, and good performances by Griffith and Wasson, who fits the B-Movie actor role well. One point I'm not really sure how the movie got from the climax to the final scene.
