Waiting two decades before seeing “The Dead Pool” (1988) was definitely a good call. It fills the movie with surprises, surprises that having nothing to do with the boilerplate Dirty Harry plot. Liam Neeson! Too bad his character is a throwaway. Jim Carrey! (I’m sorry, the credit says “James.”) Too bad he dies. Patricia Clarkson! Too bad she’s not a redhead, but anything’s better than Sondra Locke. A “Bullitt” car chase! Too bad it’s with an RC car. Clint Eastwood wearing the sunglasses the optometrist gives you after he dilates you! Too bad Clint apparently thinks they’re for everyday use.
