However, this adaptation directed by Will Gluck (“Easy A,” the best-forgotten “Annie” remake ) and co-written with Rob Lieber (“Alexander and the Terrible, Horrible No Good, Very Bad Day”) remains semi-faithful to the source material—at least for the first 10 minutes or so. After all, it is a fairly short book. In this padded version, the now-orphaned Peter recruits his triplet sisters, Flopsy, Mopsy and Cottontail (spoken by Margot Robbie, Elizabeth Debicki and Daisy Ridley—not that you can tell) along with their chubby cousin Benjamin (Colin Moody), to assist in staging a major heist. The elderly McGregor (Sam Neill, barely recognizable behind a bushy gray beard and extra body padding) is initially oblivious—until he turns off his loud lawn mower. But just when it looks as if he has trapped his prey, the gardener suddenly drops dead. It seems the rake-wielding hot-head was a junk food junkie—oh, the irony, given his struggles to protect his bountiful crops.
