5. NBC Wanted to Take Over ‘Batman,’ But ABC Dismantled the Bat Cave — Things You Didn’t Know About Batman
'Batman' only lasted three seasons after the novelty wore off and ABC decided to cancel the campy series. However, there was a chance that another network might be interested in picking up the show, so ABC kept the iconic set in place as they waited for offers. A couple of weeks passed and no offers materialized, so the network ordered that Batman’s “Bat Cave” and other sets be demolished to make way for another show.
Just as the crew finished taking the set apart, NBC submitted an offer to take over the show for another season. Unfortunately, the sets had been destroyed and the Bat Cave alone would cost $800,000 to rebuild, so NBC rescinded the offer.
