Luc Besson has produced this moderate gung-ho actioner about a roistering bunch of US special forces soldiers in Sarajevo in 1995, kicking war-criminal ass, taking courageous risks that are intensely frowned on by the uptight and incompetent “SAS” Brits in overall charge and then discovering there is a fortune in looted Nazi gold at the bottom of a lake, which the Germans abandoned there in 1944.

The navy Seals’ plan is to secretly bring up these bullion bars, while on enforced leave, and (having somehow found a cash buyer) split the take 50/50 between them and a beautiful Bosnian woman who had tipped them off about the stash. She wants to use the money for her charitable foundation. So our heroes have hearts of gold, too. There is a spectacular scene in which someone drives a tank off a bridge, and JK Simmons gives the film some ballast as the guys’ scowling commanding officer, but the rest of the time this resembles a TV movie of egregious averageness.
