The Smurfs and the Magic Flute (Unproduced dubs)

The Smurfs and the Magic Flute (French: La Flûte à six schtroumpfs, lit. The Flute of Six Smurfs) is a 1976 Belgian animated film starring the Smurfs, directed by their creator, Peyo.

Dubbing History
Although the film premiered in 1976 in Belgium, two English-language versions were released in 1979 in the United Kingdom, and in the United States in 1983. Both versions have completely different voice casts.

Throughout the late-1970s, when dubbing this film in another language, the French ending credits and the "Once upon a time..." text were left in French until 1979, when they were both translated to English. Other language dubs got re-dubbed again in 2011 (examples: Spanish, Hebrew).

There also exist two different restorations of the film (both are in 16:9 widescreen). The 2011 restoration uses new opening credits placed in a brown background. This is true for the English and French versions. However, in 2019, a new restoration was created using the French version's 35mm transfer (while translating the opening credits into English for both that and other dubs).
