From what I've gathered about the man, that's not too far off the mark.
Toward the later part of his career, when he started moving away from painting / print to film, he was once asked in interview why he started moving towards film.
He started explaining the process of using a camera, and, in so many words, basically told the interviewer that he got into film because a camera was easier to operate than painting a picture.
Remember, this is the guy that successfully convinced the art scene that a picture of Campbell's soup was art:
