ZAZ's approach reminds me of a three ring circus- so much going on, where should I focus? The car gag...one air bag goes off and releases the gear lever and it becomes a runaway car to the point 4 air bags pop open and seems to drive itself making a right turn and no one in pursuit. The screaming voices on the soundtrack add to the visual mayhem. Later, after the anti-graffitti wall demonstration (which was priceless) Drebin looks into the microscope until he's told to use the open eye. We hear the professor explaining about fibers and yet we're watching Drebin lower the microscope lens until the lens part breaks the slide. Again, there is so much visual and audio going on and yet we know it's part of the humor that ZAZ is going to give us in 90 minutes.
I would have to say they are different. Mel Brooks uses a more "traditional" set up to get to the gag. ZAZ is setting up so many things that there are gags within gags to get to the payoff. Overlapping visuals mixed with audio and it pays off.
Inspector Clouseau is a tad suave, sophisticated and buffoonish. He tries to hide his bumbling by acting if what he has broken or destroyed is part of his regular routine. Frank Drebin, on the other hand reacts as if he knows something is wrong, but he acts innocent and if to say he wasn't responsible for whatever is broken or destroyed.
