"There are few things more thrilling for movie lovers than being able to experience a true classic like Casablanca the way it was originally intended on the big screen," said Dennis Adamovich, the senior vice president of brand and digital at TCM, TNT and TBS.
The screenings will also receive an introduction message from Turner Classic Movies host Robert Osborne.
Casablanca starred Humphrey Bogart and Ingrid Bergman, and won three Oscars in 1944 for 'Best Picture', 'Best Director' and 'Best Screenplay'.
The list of almost 500 theatres that will screen Casablanca can be found at Fathom Events.
