Editors' Movie Rental of the Week

"The Real Cancun," a reality film directed by the shameless producers of MTV, opens this weekend in major cities-but it won't be released locally for a few weeks. Disappointed? Dry your eyes. "Cancun" advertises "sexy hijinks," which are sure to be superficial, irritating and about as smooth as a tequila shot. A racy scheme is more elegantly achieved (as elegantly as a frontrunner to teen movies can be achieved, that is) in 1983's "Risky Business." A very young Tom Cruise plays a Chicago teenager who has been left in the house alone and gets mixed up with a prostitution ring. While his pimping somehow seems innocent, he's quite guilty of taking part in a train-sex scene that's much hotter (I venture to guess) than any MTV beach party.
