1967 Wonder Woman TV "Pilot"
William Dozier was the producer of the 1966-1967 Batman television show, and he investigated the possibility of getting lightning to strike again but with Wonder Woman. What he came up with would not be considered "good" in any sense of the word, but viewing the Screen Test located over here is probably a worthwhile time investment of five minutes nonetheless. I never knew this footage existed until I came across it the other day.
You'll recognize the voice of the narrator because it's the same gent who narrated the contemporaneous Batman show. The phrase "Same bat-time, same bat-channel" was made famous by this narrator, whose identity turns out to be... William Dozier! I never knew that before either!
