One of the presumptions as to why the show has never been on DVD was that DC and WB was embarrassed about this version of Batman. But if they want to merchandise it, clearly that was totally wrong!
I hope this is a good sign of DVDs are getting closer.
I would love to see some of Adam West voice over work in batman cartoons included as extras. He voiced Batman in the last two season of Superfriends. One of which is called "The Fear". Which was written as a pilot for a Batman spin-off that never happened. It was the first time outside of the comics that Batman's origin was shown. Adam West gave a great performance. Considering his own show only gave a passing mention to Bruce's parents death it would be a great inclusion.
