Bolstered by a strong supporting cast including Neal McDonough, John Heard, Sela Ward and Clancy Brown, The Guardian is a bit on the long side (137 minutes), but it never feels slow, and a romantic subplot (with Kutcher wooing a schoolteacher played by Melissa Sagemiller) blends nicely with thrilling ocean-rescue sequences incorporating a seamless blend of CGI and footage shot in a 750,000-gallon water tank. Music fans will welcome the scene-stealing appearance of veteran singer Bonnie Bramlett as the owner of a jazz/blues club near the training base, where The Guardian serves up yet another staple of its genre: the barroom brawl. Although Hurricane Katrina prevented The Guardian from being filmed in New Orleans in 2005, real-life footage during the closing credits makes it clear that the Coast Guard was essential in Katrina's aftermath, and this rousing drama pays overdue tribute to those who risk there lives (to quote the Coast Guard's motto) "so that others may live." --Jeff Shannon
