Rather sadly, a film l will probably never see. Batman fights Dracula, a rather strange looking Filipino offering that is now considered lost.
I know it will probably be crap, but l can imagine it being soooooo buttock clenchingly bad, it will be hilarious.
I also think Adam West (and his costume) must have been unavailable at the time of shooting.
On a related note, here's a comic strip that not many have seen - Dragula,Queen of Darkness (from here). Originally featured in National Lampoon 1971.
