For anyone who didn’t understand Toy Story’s metaphor the first time around, Marla Frazee’s picture book becomes a more literal interpretation that still manages to be fairly charming. Imaginative 7-year-old Tim (Miles Christopher Bakshi) is content with his life as beloved only child, until his life is turned upside-down by the arrival of a new baby (Alec Baldwin)—whom he sees as a tiny, demanding executive in a suit and tie. The parents see the baby that way, too, which muddles things a bit, and it is essentially a re-tread of the Woody/Buzz sibling jealousy dynamic played out in another broad adventure; Boss Baby even compares Tim to an “old toy” and describes himself as “the hot new thing.” But director Tom McGrath (the Madagascar series) offers up plenty of engaging world-building, including a Rube Goldberg-esque heavenly factory floor for baby delivery, binkies that send the users on vision quests and pop-culture nods to everything from Raiders of the Lost Ark to Mojo Nixon. The lively sense of humor keeps churning along, enough to distract you from the “old toy” embedded in this hot new thing. By Scott Renshaw
