What’s new on Blu-ray Disc this week? Warner Bros. celebrates the 70th Anniversary of Cassablanca with a limited edition boxed set containing two Blu-ray Discs, one DVD, a reproduction of the original film poster, 62-page hardcover booklet, and other extras. The classic 1942 film stars Humphrey Bogart, Ingrid Bergman and Paul Henreid and is regarded as one of America’s favorite films of all time. On the other side of the spectrum, the latest Alvin and the Chipmunks movie “Chipwrecked” has been released. The Blu-ray Disc edition contains both a DVD and Digital Copy of the film. And, you can’t help but get a little teary eyed when mentioning the 1992 film The Bodyguard, starring Kevin Costner and the now deceased Whitney Houston. The film hit theaters as Whitney was emerging as one of music’s biggest stars and included a soundtrack that broke the charts with Houston’s rendition of “I Will Always Love You.” See below for our Blu-ray picks this week.
