The actors who portrayed Batgirl, Catwoman, and the Riddler in the 1960s Batman television series also appeared in Star Trek: The Original Series. Batman and TOS both began in 1966 and appealed to similar audiences, so it’s not surprising that several actors popped up on these two shows. With its campy, humorous tone, the 1960s Batman was very different from most modern adaptations featuring the Caped Crusader. As Batman (Adam West) and Robin (Burt Ward) defended Gotham City, they used ridiculously named gadgets to take on villains, and comic book words like “POW!” and “BAM!” popped up on the screen during fight scenes.
