If Sylvester Stallone plays the world's number one assassin in this thriller, that must make Antonio Banderas, well, number two. The two are competing to hit the same target for a $20-million payoff and their challenge takes them from explosion to explosion on a cat-and-mouse chase from Seattle to Mexico. Julianne Moore plays the cagey cat fancier and computer hacker who possesses a stolen computer disc that makes her a prime target for bad guys, and Robert Rath (Stallone)is only too happy to come to her defense. Director Richard Donner handles action sequences with adequate flair and has a good time blowing things up. Banderas has fun with the nonsensical plot, and Moore is enjoyable in one of her big-budget mainstream roles. --Jeff Shannon
