I saw the car (and Kato's nitrous-injected Harley) at The Source in Minneapolis a few months back. Both were VERY sweet rides.
I'm still not sure on the comedic side of the Green Hornet. Yes, he was campy in the 60s (same as Batman) and it may be good. My worries are that other studios may decide "Campy Hero" is the new In thing and we're back to fighting to have them taken seriously again.
As for GH being a sidekick to Kato... Well, let's just say that's a holdover from Bruce Lee being the original Kato on the TV series. Hard to make that man a second fiddle to anyone (remember, he kicked Chuck Norris' ass).
