I'm sure I saw bits of the 1966 movie as kid in the 80's but I was never a fan of the show (it was just another half an hour that they could have be showing a cartoon
) so I didn't pay much attention to it.
Having not read the comics, the 89 Batman movie was my first experience of a darker more realistic Batman and I thought it was absolutely brilliant.
I can still remember Prince dressed as half Batman/ half Joker for the film clip to
Batdance.
