Film producer Edward Nassour co-owned Nassour Studios with his brother William Nassour. In the 1930s Edward produced a stop-motion animation short, shot in Technicolor, entitled "Knight Time", that told the story of a knight's squire named Yebo who ends up fighting a fire-breathing dragon. Nassour's pet project was an all-animated feature entitled "Ring Around Saturn", whose story was based on a project once owned by famed documentary filmmaker Robert J. Flaherty, and later by Orson Welles, who used it as a segment in his aborted RKO documentary It's All True: Based on an Unfinished Film by Orson Welles (1993). Welles sold the property to Nassour, who transformed it into a feature-length film using replacement puppet animation. The project was never finished while Nassour was alive. After his death his brother William released it in a re-edited version called Emilio and His Magical Bull (1975).

After The Brave One (1956) won the Oscar for Best Motion Picture Story, Nassour sued its producers, the King Brothers, for plagiarism on the grounds that "The Brave One"s story -- written by blacklisted screenwriter Dalton Trumbo under the pseudonym "Robert Rich," shared many aspects with the story of "Ring Around Saturn." The King Brothers eventually settled the dispute by paying a $750,000 out-of-court settlement.
