From cop movies to spy films, from "Dracula" to "The Fugitive," Leslie Nielsen has spoofed it all. Could a sci-fi parody be far behind? In this spaced-out send-up, Nielsen (who also co-wrote) stars as a bumbling security operative out to foil an alien plot to abduct and clone the president. Co-stars Ophélie Winter, Peter Egan and Alexandra Kamp-Groeneveld. 98 min. Standard; Soundtrack: English Dolby Digital 5.1; Subtitles: English; theatrical trailers.
