As Europe and North Africa served as battlegrounds for World War II's Western front, the film "Casablanca" premiered in U.S. theaters in 1942.

Now, 70 years later, it will return to the big screen again - a one-night event celebrating the movie classic's enduring legacy.

Broadcasting in nearly 500 theaters across the country, "Casablanca" will have two showings at several theaters in the Austin area, with a matinee at 2 p.m. and a later show at 7 p.m. It is presented by NCM Fathom Events.

Dubbed the "Turner Classic Movies Presents Casablanca 70th Anniversary Event," the showing will begin with an introduction from TCM host Robert Osborne.

Osborne will discuss why "Casablanca" is still a popular film, as well as present some behind-the-scenes stories about the filming of the movie.

"Casablanca" starred Humphrey Bogart and Ingrid Bergman as two former lovers fighting to survive in Casablanca during World War II. Bogart's character, Rick Blaine, an American running a nightclub there, sticks his neck out for no one.

But he finds himself conflicted after Bergman's character, Ilsa, walks back into his life needing someone to help her husband, a Resistance leader wanted by the Nazis. She offers herself in exchange for his transport to the United States. Rick is saddled with a choice: personal happiness or a crucial role in the Allied cause.

The film won three Academy Awards in 1944, including one for Best Picture, and is considered one of the best love stories of all time.

Tickets for the showings are $12.50 and available at participating theater box offices and online at www.FathomEvents.com.

Austin theaters participating in the screenings include Southpark Meadows, Cinemark Hill Country Galleria, Tinseltown USA Pflugerville, Stone Hill Town Center and Cinemark Cedar Park.
