During the song "I'm Mean" Bluto picks up large chair. Three people standing by a window disperse to avoid being hit by it when Bluto turns to throw it out the window. Bluto throws it, but when the camera cuts back to the window, it is not the chair that goes through the window, but a small barrel.

When Wimpy sits down at Popeye's table during the diner scene, two ketchup bottles are present. Each time the shot switches perspective, one of the bottles keeps going from half-full to completely full.

When Oxblood accidentally knocks out his mother and hits Popeye in the stomach, Popeye goes rolling backwards, but in the next shot he's rolling forwards into the ropes.

In the climax, when the octopus is pulling down the boat with Swee'Pea inside, Olive's dress can be seen in the right-hand corner of the screen in the underwater shot (widescreen version).

When Bluto is feeding Popeye the spinach in the end, his pipe disappears, then reappears.

Filled and closed tin cans do not float.

At the boxing match, the banners say "worlds only floating arena" without the apostrophe in "world's".

Bluto easily swims with the treasure chest over his shoulder: it should push him down into the water.

Though obviously for comedic purposes, the velocity of Oxblood Oxheart's kick when he boots Caster Oyl out of the ring would've barely made him fall out of the ring, not fly off to who-knows-where.

The baby bottle's nipple defeats the very purpose of sending a message in a bottle as it will get wet. However, it is all Popeye seems to have to seal the bottle, and if not deformed by sucking it should keep water mostly out especially as the bottle floats.

As per the info in the trivia section of this film, the makeup and appliances for Popeye's massive forearms were not ready, so in some scenes, especially the boxing match, it's visible that the insides of his forearms are merely flesh-colored pads tied over Robin Williams' arms; the strings are visible.

During Popeye's boxing-ring fight, the large banner at times has mirror writing, suggesting that the shot has been flipped. However, wider shots clearly show that the ring has banners on opposite sides, made in a way that lets them be read from the back. The view from inside the ring will always appear reversed.

At approximately 54:25, Oxblood Oxheart kicks Castor Oyl out of the ring. As Castor flies through the air, past the camera, the image shakes, indicating that the prop body hit the camera or its platform.

Obvious mannequin when Castor Oyl is thrown off the boxing ring at 54 min.

At 1:14:20 obvious fake pelican when Wimpy gives Swee'Pea to Bluto.

The Paramount logo used at the opening was never used for any of the Paramount Popeye cartoons, though it is portrayed as being from a Popeye cartoon. Also, the opening-credits sequence shown (doors of the wooden ship) is from the earlier Fleischer Studios cartoons, as opposed to the later Paramount cartoons.

When Bluto is beating up Popeye and making threats of how taxed the Oyls will be, Bluto's mouth moves not at all.

The first time Olive comes up from under the water as she's fighting the octopus, she screams, "HELP! HELP!" but her mouth movements show clearly that she's simply gasping for air.

At 1:18, Bluto's burp when sleeping doesn't match the movements of his lips or abdomen.

When Bluto climbs his ship to announce curfew, the battery pack for his mic is visibly attached to his back, underneath his long underwear.

Obvious board under the taxman's back when he is sliding down the slide and into the water (not visible just before and falls backwards and not visible anymore when he is in the water).

At 10.35, the lights are briefly seen in the reflection of Nana Oyl's glasses.
