This is essentially an updated Abbott and Costello film for 1969 with Rowan and Martin standing in for Bud and Lou. The plot has the boys wandering around a "haunted" house looking for hidden jewels while trying to remain alive and avoid "werewolves" and "vampires". Its a weird mix of comedy horror and mystery put together in a psychedelic blender. Its very much of the time, and of Laugh-In with the brand of humor that was a huge hit on TV interlaced into a murder mystery. Forgive me I have no idea how to explain this movie except that its a bunch of very good actors being very silly, I mean where else can you see Fritz Weaver channeling Bela Lugosi for giggles? The humor is uneven, with some of the jokes dating badly to the point that unless you lived in 1969 you won't get the joke. Its an odd film. I don't know if I can really recommend it, though if you like Laugh-In you stand a good shot at enjoying this 90 minute fluff ball. (though I do have to point out I grew to dislike Dan Rowan's character a great deal since he was much too mean spirited and sleazy for my tastes)
