To take place April 22-25, the film series is billed as "a landmark celebration of the history of Hollywood and its movies, presented in a way that only TCM can, with major events, celebrity appearances and screenings of classic movies."
All screenings -- more than 50 in all -- are to include special introductions to provide context about each film.
Specific details about the festival are expected to be announced in the weeks and months ahead, including appearances by actors, actresses, directors, producers and other key figures.
Robert Osborne, TCM's prime time host, will be the official emcee of the festival.
"Classic movies are something that link the past to the present and form a vital part of our culture," Osborne said in a statement Wednesday. "This new festival will give those who love movies a way to connect with each other. It is a first-of-its-kind chance for TCM fans to experience the network in-person, meet others with the same interests and immerse themselves in a wide array of classic films."
