You're forgiven if the title of the new Harrison-Ford-saves-his-family thriller doesn't exactly get your pulse pounding. As used here, ''Firewall" is an Internet security term, which is like naming an action movie ''Proxy Server!" or ''SOCKS Protocol." It promises not car chases but pale IT technicians staring into banks of computers.
Actually, we get both, since Ford plays Jack Stanfield, a Seattle network security exec who has to rob his own bank via computer if he doesn't want the bad guys to kill his wife (Virginia Madsen) and kids (Carly Schroeder and Jimmy Bennett). As directed by Richard Loncraine (''Richard III," ''Wimbledon"), the movie's competent stuff, but it also represents professionalism in the service of absolutely nothing. Even Ford knows he's been down this road too often; his performance has a grim intensity and not a shred of spontaneity.
