Popeye the Sailor (animated cartoons) Popeye the Sailor is an American animated series of comedy short films based on the titular comic strip character created by E. C. Segar. In 1933, Max and Dave Fleischer's Fleischer Studios adapted Segar's characters into a series of "Popeye the Sailor" theatrical cartoon shorts for Paramount Pictures. The plotlines in the animated cartoons tended to be simpler than those presented in the comic strips, and the characters slightly different. A villain, usually Bluto, makes a move on Popeye's "sweetie," Olive Oyl. The villain clobbers Popeye until he eats spinach, giving him superhuman strength. Thus empowered, the sailor makes short work of the villain.
