According to French Wikipedia, the Dungeons & Dragons animated series premiered in France in 1984 (IMDb says 1987, as do other sources), and was rebroadcast starting in 1986. The series was called Le Sourire du Dragon (The Smile of the Dragon), as was the song used for the intro, sung by Dorothée. Listen to the full version here, and watch the actual intro here. It’s very sweet, but also kind of creepy, maybe because it reminds me of the Twin Peaks soundtrack.
The game was designed by François Marcela-Froideval, an influential figure in the introduction of RPGs in France. He came to the U.S. in 1982 to work for TSR, where he collaborated with Gary Gygax on Oriental Adventures (1985), among other projects.
Tignous is credited as the interior artist, and comics innovator Bill Sienkiewicz painted the cover. Sienkiewicz got his start on Moon Knight and The New Mutants, and went on to do mind-blowing art for Elektra: Assassin and the Daredevil: Love and War graphic novel, both of them written by Frank Miller.

I wonder why this was never released in the U.S. Seems like the series was more popular overseas.
The U.S. got a different, sillier game:

It’s interesting to look at the products and ads released in the different markets. The Europeans got the more sophisticated fare.
