Sort of a forerunner to Chuck Jones's more famous "Duck Amuck", "A Cartoonist's Nightmare" portrays an animator working on a Beans cartoon. He falls asleep and ends up in the cartoon, where the monster threatening Beans proceeds to menace the cartoonist. It's up to Beans to save the day!
This short, directed by Jack King (previously a Disney animator, he soon returned to Disney, after which Frank Tashlin took over his unit), came out right after Friz Freleng's "I Haven't Got a Hat", which debuted not only Beans but also Porky. If I remember right, Porky and Beans were officially a team (pork and beans, get it?). Needless to say, Beans quickly dropped off the radar, while Porky gained fame as WB's first bona fide cartoon superstar, although he soon got overtaken by a certain stuttering duck, and later by a wise-guy rabbit.
Anyway, this one's OK as a historical reference.
