Incredible though it may seem, Clint Eastwood will be 80 (!) on May 31.

To celebrate, Turner Classic Movies will pay tribute to the iconic actor/director with a 24-hour marathon of his movies.

Beginning at 6AM with 1956's 'The First Traveling Salesleady,' the cable network will run many fan favorites, including 'Dirty Harry,' 'Magnum Force' and 'Hang 'Em High.' In addition, the network will air 'The Eastwood Factor,' a documentary narrated by his 'Invictus' star, Morgan Freeman.
