Joann Sfar's not the first (or the last) comic creator to make the transition to movie-making, but a recent interview for the Wall Street Journal on his French film Gainsbourg the artist-turned-director laments about the difficulties of comics versus that of film.
"It’s actually more difficult to do a comic book than a movie," Sfar told WSJ's Nick Andersen. "If something doesn’t work in a movie, you can blame the crew or do it again. If it doesn’t work in a comic book, then it’s your fault. I know I have many things to learn in movies, but I had so much fun making the movie. Comic books may not have been useful for making a movie, but drawing was. My crew all had more than 20 years of experiences, and I’m a newbie. So I didn’t come with orders, I came with graphical suggestions. There are visual propositions in the film that may be appealing for the studio people."
Sfar goes on to explain that when creating the animated film The Rabbi's Cat, the production of animation was much slower than drawing comics, comparing his page rate of five pages per day as a cartoonist with an animator's typical rate being one second of film per day.
