Here's a very rare 1936 Looney Tunes short. "Boom Boom", directed by Jack King, was one of the short-lived "Porky and Beans Gang" series, and one of the few to pair the two characters together as adults. I'm not positive who voices Beans here, but Joe Daugherty is the voice of Porky, and Billy Bletcher can be heard as the voice of one of the enemy soldiers interrogating "General Hardtack".
These early black and white experiments with the "Beans Gang" are interesting, because they fall somewhere inbetween the bland, gentle comedy of the Buddy cartoons and the more formative Porky series that brought about the kind of humor Looney Tunes are still known for today. You'll also notice that the war gags are very World War I based...WWI was over, but WWII was several years away.
Enjoy this hard-to-see early Porky cartoon!
