Hey, Frank Sinatra made World War II movies – why not Jon Bon Jovi? The younger New Jersey pop star plays a supporting role in “U-571” (2000), in which a group of American submarine sailors carry out a secret mission against the Germans. The Yanks – and the movie, for that matter – are led by untested skipper Matthew McConaughey. Not to worry, because Harvey Keitel, David Keith and Bill Paxton are there to lend ballast to the neophyte leading man. The film is boilerplate war movie stuff – ragtag bunch faces adversity, yada, yada – and (spoiler alert) we all know how WWII ends.
