For the three-day weekend, Hollywood is going back to the futuristic.
"Men in Black 3" is the sequel you didn't know you wanted - and it's better than the first movie (which isn't as good as you remember; go back and watch if you doubt it). Will Smith's Agent J discovers that a nasty alien (Jemaine Clement) has gone back in time and altered history, killing his partner, Agent K (Tommy Lee Jones). So J goes back to 1969, and teams with a young K (well played by Josh Brolin) to put things right. Director Barry Sonnenfeld brings back the swanky retro look, and throws in a great performance by Michael Stuhlbarg as an alien who can visualize multiple futures. Not all the jokes hang together, but Smith's cool confidence keeps you watching.
The other big studio movie of the week is "Chernobyl Diaries," a found-footage horror thriller co-written by "Paranormal Activity" director Oren Peli. It was not screened for critics.
