The 7th Voyage of Sinbad is a 1958 American Technicolor heroic fantasy adventure film directed by Nathan H. Juran and starring Kerwin Mathews, Kathryn Grant, Torin Thatcher, Richard Eyer, and Alec Mango.

All three Sinbad films were conceptualized by Ray Harryhausen using Dynamation, the full color widescreen stop-motion animation technique that he created.

The 7th Voyage of Sinbad was selected in 2008 for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant".

[5][6] Sinbad the Sailor and his ship's crew make landfall on the island of Colossa, where they encounter Sokurah the magician fleeing a giant cyclops.

After reaching Baghdad, Sokurah performs magic at the pre-wedding festivities, temporarily turning Parisa's handmaiden into a snake-like being.

Later that night, Sokurah secretly shrinks the princess, enraging her father, the Sultan of Chandra, who declares war on Baghdad.

Sinbad and the Caliph give in to Sokurah, who explains that the eggshell of a Roc is needed for the potion that will restore Parisa, and it can be found only on Colossa.

While the men are eating, Parisa enters the magic lamp and befriends Barani, the childlike genie inside, who tells her how to summon him in exchange for her promise of his freedom.

With the help of the genie, Sinbad and Parisa make their way out of the cave, stopping to destroy the lamp by throwing it into a pool of lava, thus freeing Barani.

In a final act of magic as he was being freed, Barani filled the captain's cabin with the treasure from the cyclops' cave, a wedding gift to Sinbad and Parisa.

[8] It took Ray Harryhausen 11 months to complete the full color, widescreen stop-motion animation sequences for The 7th Voyage of Sinbad.

[9] Harryhausen gave the cyclops a horn, goat legs, and cloven hooves, an idea based upon the concept of the Greek god Pan.

[10] Harryhausen researched the cobra-woman sequence (when Sakourah entertains the Caliph and the Sultan) by watching a belly dancer in Beirut, Lebanon.

The cyclops is the film's most popular character, but Harryhausen's personal favorite was the cobra-woman, a combination of Princess Parisa's maid, Sadi, and a cobra.

Of the four, Harryhausen regarded the score for The 7th Voyage of Sinbad as being the finest, due to the empathy Herrmann's main title composition evoked for the subject matter.
