The Princess of the Dragon

"The Princess of the Dragon" was an animated feature film developed by Columbia Pictures that was first released in Europe in 1976 and later in America in 1983, when it was dubbed into English. Because it was developed by a production company other than Hanna-Barbera and it does not tie in with any of the stories featured in the Smurfs cartoon show, it is considered a "non-canonical" Smurf story.
