Just found this rare Warner Bros.-Looney Tunes cartoon on YouTube. "Supervised" by ex-Disney animator Jack King (though he'd later return there as the new resident Donald Duck helmer), A Cartoonist's Nightmare is one of the few that starred a now-forgotten character named Beans the Cat who was first seen in Friz Freleng's color Merrie Melodies short, I Haven't Got a Hat, which also introduced Porky Pig. In this one, with all the other animators having gone home, one particular cartoonist stays on trying to finish his drawings on time. As he draws bars on Beans to protect him from a monster, the animator goes to sleep and dreams of getting attacked by other villains he created. It's up to Beans to rescue him...Lots of clever creative ways of drawing and erasing escapes abound here and while nothing hilarious happens, I was constantly amused at this early version of Duck Amuck that Chuck Jones made with Daffy Duck 18 years later! On that note, I recommend this for any Warner cartoon completists out there.
