This is a genuinely clever comedy helmed by an inspired comic duo, Tommy Lee Jones and Will Smith. Smith is the funny man to Jones' straight man, yet even the straight man -- rigidly straight, in this case -- is funny in this movie. The plot? Well, what if there were hundreds of extra-terrestrials living among us on Earth right now? Jones is in charge of keeping these aliens in check, preventing any global disasters the nasty ones might cause. Smith is Jones' recruit, an agent-in-training. The comedy is nonstop and the special effects are as good or better than what one finds in most straight science fiction films.

The movie is, however, is much too short, running at a mere 96 minutes and feeling like less. Men In Black is simply too fun to be crammed into an hour and a half.
