I revisited this movie in honor of Danielle Darrieux, who died a few days ago at the age of 100. She does the voice for the grandmother. Darrieux was 90 when they made the film. Catherine Deneuve played her daughter (not for the first time), Marjane's mother, and Chiara Mastroianni, Deneuve's real-life daughter, played Marjane.
Satrapi and Paronnaud decided to record the voices of the main characters before they did the drawings (Satrapi, of course, did the drawings in the original graphic novel), which was interesting. I hadn't thought of the implications for the English-language dub until I watched a making-of featurette. Those voices were done in the usual fashion, with the voice actors speaking in time to the animated characters. I've never seen the English version, and while I'm sure it's good, the point here was to watch Darrieux. (Deneuve and Mastroianni did the English voices, too.)
Darrieux said of the grandmother, "She's an uninhibited character, who's not afraid of anything. She's politically incorrect and a straight talker. I love talking dirty, so I felt really comfortable with the character!"
I've written about the movie before, and didn't see anything in particular to change my mind, other than enjoying Darrieux a bit more knowing she had finally died. #177 on the They Shoot Pictures, Don't They list of the top 1000 films of the 21st century. 8/10.
