Like many of the films from Hal Roach Studios, this one was directed by James Parrott--also known as Paul Parrott. Parrott was a comedian and starred in quite a few shorts. However, unlike his more famous brother (Charley Chase), after a while he stopped acting and concentrated on directing....whereas Charley continued to do both during his time at Roach.
"Mixed Nuts" is a single-idea comedy that really doesn't make the most of that idea. When the story begins, someone leaves $2,000,000 for the training of chorus girls to learn another life. The rest of the film is set at a finishing school where the lovely young ladies have matriculated. The problem is that most of what happens next isn't all that funny--the self-defense class, the sleepwalking bit, the art class as well as the lady with bugs in her clothing. Barely a laugh in any of these routines....and reason enough to skip this one.
