For years, video-game designers have been making crappy game versions of popular Hollywood movies. Consider Xavier Gens' actioner Hollywood's revenge. The four incarnations of the popular Hitman game are slick, complicated role-playing titles where you take on the role of Agent 47, a trained-from-youth assassin. The film version is anything but. Deadwood's Timothy Olyphant, though a fine actor, is miscast as the brooding killer, spewing witless dialogue. Basing a movie on a video game or game character is a dicey proposition in the first place. Critics may tag Hitman as suitable only for fans of the game, but the dedicated gamers who have waited to see this movie will probably be the most disappointed of all.
