I didn't see the whole Batman serial at the movies in the '60s, but I did see chapter one a few years later as part of a Columbia shots hodgepodge released theatrically in the '70s. It was called THREE STOOGES FOLIES or something. The Stooges headlined, but there were also shorts from others like Edgar Kennedy and maybe Leon Errol and that chapter of Batman was thrown in too. Pretty hilarious seeing them fight in fast mostion in those clunky costumes, but still the highlight of the show for me since I'd never seen any of the serial before.
