The premise to "A Bathtub Bandit" isn't very good nor does it make sense...even for a comedy. To make matters worse, it's not a particularly good film either.
Ham and Bud (Lloyd Hamilton and Bud Duncan) are tricked into helping the Bathtub Bandit steal yet another bathtub. Now you might be wondering...why would anyone want to steal bathtubs...and I wondered the same! Later, the pair realize the guy was a crook and they set out to catch him. This includes a lot of mindless slapstick...with wild shooting, chases and violence...instead of plot or story.
The story makes no sense, there are very few laughs....so it's not exactly a film I would recommend. Perhaps you'll enjoy it...I didn't.
