This film is absolutely hilarious but those who aren't into the detective genre might find their enjoyment diminished. I say this because if you have watched any films involving the characters that are being spoofed you will appreciate how dead on the satire is. Peter Sellers' Charlie Chan alike is particularly well observed and the host Lionel Twain's constant correction of his grammar really points out the terrible acting of the actual films. Having said this however much of the film is just out and out funny to almost anyone, I particularly liked the revelation of what motive Sam Diamond has for the murder. My one tiny criticism is that the scene where the murderer is revealed would have been much funnier if it had stopped 3 revelations earlier (you'll see what i mean when you watch it)! Overall i'd give it a 8 out of 10 generally and a 9 out of 10 if you're a detective fan.
