New pilot being aired in the US later this month, personally think Eddie Izzard is a fine actor and comedian. NBC still haven't committed to a series because of the cost of the special effects, waiting for the ratings no doubt.
However I'm a little unsure about this myself, I loved the Munsters as a kid. After watching an episode on youtube, I now realise it was corny and predictable and totally carried by Fred Gwynns mannerisms and facial expressions (kudos to the casting agent). I wonder if Eddie Izzard in the (Al Lewis) role of Grandpa can do the same, because I've seen Jerry O'Connell (Herman) in a couple of things and he has all the acting skills and charisma of a wet fish.
