Not very good. Most notable for the constant placement of Macintosh computers and related stuff (MacUser Magazine, Apple Computer Boxes, etc.). Lame story poorly acted.
Leonard Maltin/Plot synopsis:
Long, loud, loose cannon of a movie about a spoiled-brat Hollywood star who attaches himself to a reckless N. Y. C. street cop to prepare for his next movie role. Some laughs, lots of action, but it all goes out of control. Panavision.
