‘Potter’ finale on DVD

Available this week on DVD:

“Harry Potter and the Deathly Hallows, Part Two”: The smashingly good final installment in the long-running series based on J.K. Rowling’s books has Harry reaching his climactic showdown with the Dark Lord. (2:10; PG-13 for some sequences of intense action violence and frightening images) • • • 1/2

“The Change-Up”: Inventive comic performances from Jason Bateman and Ryan Reynolds as a straight-laced family man and his slacker best pal get flushed away in toilet humor. With Leslie Mann as the underappreciated wife and Olivia Wilde as the smoking-hot legal assistant. (1:41; R for pervasive strong crude sexual content and language, some graphic nudity and drug use) • •

“Atlas Shrugged Part 1”: The first installment of a planned three-part series adapted from the 1957 epic by Ayn Rand – philosopher and romance novelist of free-market capitalism – is speechy, preachy and just a teeny-weeny bit naughty. With Taylor Schilling, Jon Polito and Grant Bowler. (1:42; PG-13 for a scene of sexual content) • •
