Cindy Williams (of Laverne & Shirley fame) did a podcast a little while back where she says she was offered a role in Charlie's Angels before she went to Laverne & Shirley.

I wonder what role they actually offered to Cindy?

Cindy was very attractive in a 1974 episode of Cannon. She had really gorgeous long hair and it suited her so well. After seeing how she looked in that episode, I could easily see her being cast as one of the Angels.
