Admit it: Whenever you see or hear the title of this new flickshowcasing ultra-buff Vin Diesel as extreme-athlete-turned-secret-agent Xander Cageyou half hope it refers to the rating. No such luck. In this film by Rob Cohen (who directed Diesel in last years hot-rod spectacular The Fast and the Furious), X Games collide with a James Bond for the 00s. Stunt fans will love this picture, in which Diesel does such things as ride a metal tray down a handrail, flee from snowmobiles on a snowboard and has a fire fight in a bona fide castle. The story has something to do with some rogue Russian soldiers starting a terrorist team in the Czech Republic. The exotic locations, including some nice views of Prague, are a plus. Super-bad Samuel L. Jackson and eye candy Asia Argento add to the movies appeal. As for Diesel, he couldnt be more Diesel: all fueled up and with everywhere to go. Action-film fans could do worse than this.
