Blooper

Sinbad's ship in the night exterior shot, before they reach the island the first time, is obviously a completely different ship than the one visible during the day time in the next scene. The ship seen for the first time has only one large triangular sail as was common with medieval Mediterranean vessels. The second one, which also looks bigger, is a 16th century galleon with three square sails on three separate masts.

A different man grabs the king cobra. Sokurah reaches into the basket to pick up the cobra during his magic act. A switch to closeup shows a man with different sleeves, and three-to-four closeup frames show a hairy-headed man. Sokurah the magician is completely bald. When Sokura throws the serpent into the jar, it is blue-colored, not brown. (This is not a problem in the correctly framed 1.85:1 theatrical aspect ratio, only the full frame version.)

When Sinbad knocks out the first mutinous sailor, the sailor's position changes.

A second wooden keg appears next to the first mutinous soldier Sinbad knocks out.

Throughout the movie Princess Parisa has a little curl on her forehead (her left side). It mysteriously disappears and reappears at any given time within one scene, not just as a result of wardrobe change or scene change.

When the first scene is shown of Baghdad, the name of the city is misspelled as Bagdad.

Crossbows were considered undesirable foreign weapons in the Middle East prior to the 14th Century. Arabian warriors did not use crossbows. Use did not become common among Muslims until the Moors lived in Spain. In the time the writings of the One Thousand and One Nights, the crossbow did not exist in Arab society.

Prior to the marriage of the Princess and Sinbad, they were alone together and kissed. This would have been strictly forbidden in Islamic society in the Middle Ages, the period from which the legend was written.

After the mini-Parisa manages to push the wooden bolt out of the lid of the Cyclops' cage, Kerwin pushes the lid open. Although many viewers have joked that the lid would knock Parisa off the cage or crush her, she actually has enough time to move safely out of the way.

Road with a neatly planted row of trees in the distance behind Sinbad when he wakes up in the Roc's nest on the supposedly wild island of Collossa.

It's not that wild. It has a castle. Trees are not out of place.

On their first encounter with the cyclops, they are rowing out to their boat when the cyclops hurls a boulder at them. The boulder hits the water, makes a splash, but then it starts to float rather than sink like a rock.

When Sinbad, the Sultan, and Sokurah are in the courtyard planning the return to the cyclops island, there is a small modern house on the hill in the background.

In his close-up on the poop deck, Karim's big hoop earring can be clearly seen to be tied to his (unpierced) ear by a string emerging from his bandanna.

When Sokurah reaches toward the camera to grab the princess, his hand can be seen closing on nothing as the scene cross-dissolves to Sinbad in the Roc's nest.

Modern buildings visible in the background while the second boat from Sinbad's ship first approaches Collossa (during the dissolve to the next shot).

During the mutiny, Sinbad grabs the princess's home,turning it sideways before sticking it in his waistband and then having a violent fight. The princess would surely be dead after such treatment.

The princess wears a dress, during the magic show ceremony, that has an obvious long zipper in the back. Clothing zippers did not appear until the 20th century.

In the opening segment, when Sinbad's ship drops anchor, the anchor is a metal fluted anchor attached to a metal chain. Fluted metal anchors and metal anchor chains did not appear until the early 19th century. Until then anchors tended to be stones and were attached to heavy ropes.

Sinbad legends date from the 17th century.

During the mutiny, Sinbad's third punch misses, but is heard to connect.

Bagdad (Baghdad) is not located on the ocean. It is an inland city on the Tigris River, approximately 400 miles from the Persian Gulf.

Not only does the outfit the princess is wearing shrink with her, but apparently the rest of her wardrobe does also, because there is not enough time to have fancy outfits that fit her, with accessories, made before they sail.

The presence of a genie with clear limitless wishes for the holder of the lamp means: he could easily transport everyone to safety or return the princess to normal size.
