“Sweeney Todd” is an interesting movie. Fans of director Tim Burton will love it, but the general public many not find it entertaining. Basedon the famed Stephen Sondheim musical, the ultra-quirky tale set in the 19th century is a dark-humor extravaganza about a wronged man’s lust for revenge that drives him to murder. Burton mainstay Johnny Depp stars; Helena Bonham Carter plays his partner-in-crime. Both sing as they plot and kill. Some “Sweeney Todd” traditionalists will loathe that some songs in the stage version aren’t in the movie. What can you do when Hollywood grabs hold of your favorite play? This DVD set has a separate disc with lots of extras including information about the film’s press tour, a photo gallery, audio commentary and deleted scenes. Price: $39.99 Rent or buy: Buy if a big fan, otherwise rent.
ALVIN AND THE CHIPMUNKS
It’s hard to believe, but plans are being made for a sequel to this live-action film based on the cartoon of the same name. Yes, many people actually went and saw this movie in the theater. A struggling musician (played by Jason Lee) opens his home to three talented chipmunks; almost overnight they are a music sensation. Of course, a greedy corporate producer tries to exploit the trio and hilarity and mayhem ensue. The plot line is tired, but, given that it’s primarily for kids, it doesn’t have to be rocket science. The DVD includes three making-of featurettes; on Blu-ray, there are a few more extras. Price: $29.98 standard; $39.98, Blu-ray. Rent or buy: Rent.
