Arnold Schwarzenegger plays a federal marshal dedicated to the witness protection programin this case he’s protecting Vanessa Williamsin an enjoyably paranoid kick-ass adventure romp (1996) with some giddily hyperbolic action moments. Charles Russell (The Mask, A Nightmare on Elm Street 3: Dream Warriors) directs a limited but serviceable script by Tony Puryear and Walon Green and puts costars James Caan, James Coburn, and Robert Pastorelli through predictable paces. Schwarzenegger and Williams are regarded as blocks of decor that occasionally emit dialogue when they’re not diving out of airplanes, fighting off alligators in Central Park, evading fancy weapons and explosions in Washington, D.C., and on the Baltimore docks, and carrying out elaborate impersonations to defeat the treasonous feds on their tail. A few of the set pieces are fussy or overly extended, but the rest is tolerable bone-crunching diversion. (JR)
