The Alley Cats?
Charlie’s Angels had initially been called The Alley Cats. Part of the premise was the same with three females; however they were also living in alleys and decked out in whips and chains. What?! The cast was strongly against this title and because they had some pull with the producer, they urged them to find a new title.
Kate Jackson ultimately thought of the “Angels” title after seeing a picture of three angels hanging in producer Aaron Spelling’s office. And thus, the series was changed to Harry’s Angels. However, this too was quickly changed as the producers didn’t want any confusion with the popular detective show Harry-O.
