Great spoof of Star Trek like actors having to do it in real life. EXTREMELY entertaining, fast paced, and funny. Tim Allen as William Shatner, er, Jason Nesmith did a good job of "centering" the cast. Loved Alan Rickman (gee, is he really as stuffy as he seems?). Fun effects, especially the rock man. I'm no prude, but I enjoyed the fact that a really entertaining movie could be made without a single obscenity being uttered. By the way, Sigourney Weaver is stunning as a blonde.
