Shooting Fish is a fanciful, harmless mix of caper film and romantic comedy. Its conceits defy common sense (the protagonists trick several homeowners into believing that they are installing insulation without ever bringing the materials into the house) and gravity (they lighten a racehorse jockey with only enough helium to film a few birthday balloons). It has enough plot for two films. It loves saccharine, Burt Bacharach, and hackneyed musical montages. Actors Dan Futterman and Stuart Townsend make a devastatingly appealing pair as the film's two grown orphans with a penchant for hi-jinks. The two men approach their characters' wantonness with confidence and panache, making their various schemes seem just and venial. This is not to mention their chemistry with mutual love interest Kate Beckinsale. Shooting Fish has the insouciant tone of a film without a heavy and with a lust for life. It may not say much about its various topics -- such as orphans, criminals, the disabled, even horseracing -- but it never pretends to have a big brain, just lots of fun and a ton of heart.
