‘Casablanca’ at 70, the Blu-ray edition

You must remember this: That as time has gone by, the Oscar-winning 1942 romantic melodrama “Casablanca” has become one of the most treasured movies of the 20th century. To celebrate its 70th birthday, Warner Home Video is releasing the classic on Blu-ray Tuesday in a handsome collector’s set that features a new high-resolution digital restoration, 14 hours of bonus material and even a set of coasters.

Winner of three Academy Awards — best film, director (Michael Curtiz) and screenplay (Julius J and Philip G. Epstein, Howard Koch) — “Casablanca” revolves around Rick Blaine (Humphrey Bogart), the cynical owner of a popular Moroccan nightclub, and his former lover Ilsa (Ingrid Bergman), now married to resistance leader Victor Laszlo (Paul Henreid), with Claude Rains, Peter Lorre and Sydney Greenstreet in the supporting cast. Filmed with snappy dialogue such as “Louis, I think this is the beginning of a beautiful friendship,” the film turned tough guy Bogey into a romantic superstar.

All we can say is, here’s looking at you, “Casablanca.”
