Wonder Woman: Who's Afraid of Diana Prince? (1967)

At the height of the popularity of "Batman" (1966), producer William Dozier produced this short film in hopes of getting approval from Warner Brothers to produce a pilot episode for a "Wonder Woman" series, based on the comic book. Unlike "Batman," which was campy adventure, "Wonder Woman" was going to be a straight comedy series, along the lines of "Captain Nice." The resulting short written by several writers on the Batman series failed to win Dozier that approval.
