Popeye

Popeye (Robin Williams), a sailor, arrives at the small coastal town of Sweethaven ("Sweethaven - An Anthem") while searching for his long-lost father. He is immediately feared by the townsfolk simply because he is a stranger ("Blow Me Down"), and is accosted by a greedy taxman (Donald Moffat). He rents a room at the Oyl family's boarding house, whose daughter, Olive (Shelley Duvall), is preparing for her engagement party. Her hand is promised to Captain Bluto (Paul L. Smith), a powerful, perpetually angry bully who runs the town in the name of the mysterious Commodore. In the morning, Popeye visits the local diner for breakfast ("Everything Is Food") and demonstrates his strength as he brawls with a gang of provocative ruffians.On the night of the engagement party, Bluto and the townsfolk arrive at the Oyls' home. Olive, however, sneaks out of the house ("He's Large"). She encounters Popeye, who failed to fit in with the townsfolk at the party. The two eventually come across an abandoned baby in a basket (Wesley Ivan Hurt). Popeye adopts the child, naming him Swee'Pea, and the two return to the Oyls' home. Bluto, however, has grown increasingly furious with Olive's absence, eventually flying into a rage and destroying the house ("I'm Mean"). When he sees Popeye and Olive with Swee'Pea, Bluto beats Popeye into submission and declares heavy taxation for the Oyls.The taxman repossesses the remains of the Oyls' home and all their possessions. The Oyls' son, Castor, decides to compete against the local heavyweight boxer, Oxblood Oxheart (Peter Bray), in the hopes of winning a hefty prize for his family. However, Castor is no match for Oxheart and is savagely beaten and knocked out of the ring. Popeye takes the ring in Castor's place and defeats Oxheart, putting on a show for the townsfolk and finally earning their respect. Back at home, Popeye and Olive sing Swee'Pea to sleep ("Swee' Pea's Lullaby").The next day, Olive tells Popeye that during his match with Oxheart, she discovered that Swee'Pea can predict the future by whistling when he hears the correct answer to a question. Local con artist and hamburger enthustist Wimpy (Paul Dooley) overhears and asks to take Swee'Pea out for a walk, though he actually takes him to the horse races and wins two games. Popeye, however, is outraged, and vents his frustrations to the racing parlor's customers ("I Yam What I Yam"). Fearing further exploitation of his child, Popeye moves out of the Oyls' home and onto the docks; when the taxman harasses him, Popeye pushes him into the water, prompting a celebration by the townspeople. In the chaos, Wimpy, who has been intimidated by Bluto, kidnaps Swee'Pea for him. That night, Olive remarks to herself about her budding relationship with Popeye ("He Needs Me"), while Popeye writes a message in a bottle for Swee'Pea ("Sailin'").Wimpy sees Bluto taking Swee'Pea into the Commodore's ship; he and Olive inform Popeye. Inside, Bluto presents the boy to the curmudgeonly Commodore, promising that he is worth a fortune; however, the Commodore refuses to listen, reminding Bluto that his buried treasure is all the fortune he needs. His patience with the Commodore exhausted, Bluto ties him up and takes Swee'Pea himself ("It's Not Easy Being Me"). Popeye storms the ship and finally meets the Commodore face-to-face, realizing that he is his father, Poopdeck Pappy (Ray Walston). However, Pappy initially denies that Popeye is his son; to prove it, Pappy tries to feed Popeye spinach, which he claims is his family's source of great strength. However, Popeye hates spinach and refuses to eat it. Bluto kidnaps Olive as well and sets sail to find Pappy's treasure. Popeye, Pappy, and the Oyl family board Pappy's ship to give pursuit. Bluto sails to Scab Island, a desolate island in the middle of the ocean, while Pappy argues with his son and rants about children ("Kids").Popeye catches Bluto and fights him, but despite his determination, Popeye is overpowered. During the duel, Pappy recovers his treasure and opens the chest to reveal a collection of personal sentimental items from Popeye's infancy, including a few cans of spinach. A giant octopus guarding the treasure awakens and attacks Swee'Pea and Olive from underwater. With Popeye in a choke hold, Pappy throws him a can of spinach; Bluto, recognizing Popeye's dislike for spinach, force-feeds him the can before throwing him into the water. The spinach revitalizes Popeye and boosts his strength; he knocks Bluto down in one punch, then swiftly deals with the giant octupus, sending it flying hundreds of feet into the air. Bluto's clothing turns yellow and he swims away as Popeye and the rest of everyone else celebrates his victory ("Popeye The Sailor Man").
