A slight but likable British comedy-fantasy with a touch of naughtiness, "Cashback" is an expanded version of director Sean Ellis' Oscar-nominated short film of the same name about a bored supermarket clerk who discovers that he has the ability to stop time. Sean Biggerstaff (from the "Harry Potter" franchise) is Ben, a lovelorn young man whose chronic insomnia (due to a bad breakup) forces him to bury himself in pointless and repetitive work at a local grocery store. Once there, boredom causes him to believe that he can stop time, and he enjoys long and languid fantasies about undressing and sketching the female shoppers. But reality intrudes in the form of recollections of his troubled past, as well as the lovely presence of fellow clerk Sharon (Emilia Fox), who offers the promise of love in the real world. A gentle and artfully directed independent film, "Cashback" doesn't run very deep in terms of emotion, but the special effects are clever, the cast quirky and amusing, and its premise is an appealing mix of softcore reverie and boyish longing.
