A billionaire, teenage assassin, champion surfer, and knightly Danny McBride were no match for an animated rabbit with unnaturally large eyes, as Universal’s Hop topped the box office for the second weekend in a row with $21.7 million, according to studio estimates. The PG family film, about a teenage hare who’d rather be a rock band drummer than fulfill his duty as the Easter Bunny, slipped a mild 42 percent its second week. The live-action/animation hybrid cost $63 million to produce, and has already snatched $68.2 million. However, it may take a big hit next week when the CG-animated Rio swoops into theaters.
