Thanks to IMDB for a correction

Mister Marcel Lajeunesse for the French version was an error . It was Miss Marcelle Lajeunesse for Mizar's voice. IMDB has corrected . Thanks to IMDB.

Marcelle Lajeunesse is dead, but her name and her artistic work are respected .
The vocal artists are so important for the success of the films or series (sort of films) or cartoons in the foreign countries : they often are great theatre comedians before dubbed works and they always are great comedians. Vocal works are so difficult. They only have their voice to act in timing. Thanks again to IMDB.

I haven't her dates of birth and death. She is deceased before 1997. I search.
