6. White Christmas
1954's quintessential "Let's put on a show!" Christmas musical is a frothy holiday delight, starring Bing Crosby, Danny Kaye, Rosemary Clooney, and Vera Allen. Crosby and Kaye play a comedy duo and former veterans who tangle with sister act Clooney and Allen as they prepare for a benefit show at a Vermont ski lodge. There's fake couple scheming that turns to real love, fabulous fifties costumes, and a show-stopping finale.
