Star Trek: The Motion Picture (G, 1979)

Parents need to know that the plot concerns a nonhuman entity asking quasi-religious questions like the purpose of life, and whether there is a creator. Just as confounding: what version of this movie will you find? There are both G- and PG-rated cuts of this on video. The original theatrical release was, in fact, rated G. A harsher rating on the video reflects more the changing attitudes toward that MPAA classification than the movie content; Paramount evidently decided a G might make video consumers think this was the one where Kirk meets Barney the Dinosaur. It's worth noting that the "PG" director's-edition VHS is in letterboxed widescreen -- really the way this expensive f/x spectacle was meant to be seen and appreciated -- and has an interesting making-of documentary with the participants 20 years later, and a prolonged intro of theme music. The DVD is crammed with similar extras and commentaries.
