10 Times Actors Played Multiple Roles in the Same Movie/Show

3. Peter Sellers – Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb (1964)

Peter Sellers showcased his legendary comedic range by playing three pivotal characters in Stanley Kubrick's Dr. Strangelove: President Merkin Muffley, Group Captain Lionel Mandrake, and the titular Dr. Strangelove. What's often overlooked is the subtle brilliance of his physical transformations and vocal precision for each role. From the dignified, exasperated President to the stiff-upper-lip British Mandrake, to the menacing, uncontrollable gestures of the ex-Nazi scientist Strangelove, Sellers imbued each with distinct, unforgettable tics. Kubrick reportedly planned for him to play a fourth role (Major T. J. "King" Kong), further highlighting the incredible breadth of his planned comedic versatility.
