Rush must have been miscast on purpose. He looks about as scary as Whistler's mother and is surprisingly bad at panto villainy. Stiller wears male lead sexy gear, which only emphasises his lack of inches. As a small man trying to be angry, he is an embarrassment. Bashing people over the head with a spade is not his scene.
Wet spaniels look happier.
Azaria was the camp butler in The Birdcage. He's never less than interesting. The Blue Raj is potentially a funny character. He dresses in a turban, speaks with a phony English accent, throws forks and lives with his mom. Daft as a brush, he's left to get on with it.
