Goofs

When Francis is running with the coconut bomb, the fuse changes length between shots.

When Mrs. Robinson is swinging onto the raft, she's dumped into the ocean and soaked. In the next shot her hair is perfectly dry.

When we first get a shot of the Pirate King, he is wearing a Red Coat. Then, in the next shot, he's wearing a blue officer's coat. Colors are alternated throughout the movie.

When Father and Fritz are putting the barrels on the pig, the burlap cover falls off the pig. Father puts the barrels on the pig and suddenly the burlap cover is back on the pig.

When Father is lighting the bombs using a torch, it loses ignition and gains it again throughout the scene.

The "Quarantine" flag Father raises to drive off the pirates, a black spot on a yellow field, is actually the "India" signal flag. The actual Quarantine flag at the time would have been a plain yellow "Quebec" signal flag.

When Fritz is wrestling the snake, Ernst charges in with a machete to assist. The blade of the machete flops around revealing it is a rubber prop.

When the logs are released during the pirates' foray against the Robinsons, one of the logs rolls over one of the pirates and bends slightly as though it's made out of rubber.

When Ernst is riding the ostrich Clementine during the race, it begins to circle the pylon half way through. The rope holding the ostrich to the pylon is clearly visible.

When Fritz and Ernst are sailing, Ernst prepares to write in a journal by licking his quill pen as if it were a pencil. He does not dip it in ink.

When Fritz and Ernst capsize, there are several shots showing that the canoe has several steel lines attached to the bow holding it against the rocks.

Fritz fairly easily breaks through the door on the ship. At the time, the door would have been made of heavy solid wood and not so easily broken.

Father Robinson reads from a list of animals that have been identified, including a bear, but a bear is never seen.

A reference to Napoleonic Wars places the film's setting between 1804 and 1815. Actress Janet Munro is shown clearly wearing the straps of a 1950's-era brassiere.

The sound of rubber can be heard as the "wooden" logs are unleashed on the pirates.

When Fritz swings across the pool swapping vines halfway, just as he is landing on the rock, a crew member's hand reaches up into shot, just below his feet.

Elephants, Siberian tigers, zebras, emus and other zoo animals on a South Pacific island is hard to believe regardless of the explanation offered in the film; the fact that only a single tiger and a single elephant is observed, only makes their appearance more questionable.

Zebras are native to Africa, not Oceania or the South Pacific.

Roberta is obviously in her twenties and has breasts, yet Fritz and Ernst think she is a boy.

The crew is said to have abandoned the ship during the storm. This seems highly illogical. In the days before inflatable life rafts, the only escape vessels on board would have been small wooden life boats, similar to a canoe. It's hard to imagine a canoe fairing any better in a storm at sea than a large sailing vessel.

Even though Roberta's character hails from London, she pronounces the word "zebra" with the more commonly American pronunciation, "zeebra."

Mixture of British and American accents in the Robinson family, neither of which is fitting to their Swiss heritage.
