The 2000 Charlie's Angels film had a few totally different scripts, and when a final script was chosen, it still underwent numerous rewrites, as you can see from this August 11, 1999 early draft. Some of the craziest changes were Lucy Liu as Vivian Wu instead of Alex Munday, gay Bosley, Thin Man speaking, the original Angels' cameo, etc. The mechanical bull scene was carried over to the film's sequel, "Full Throttle".

I have also included some designs for the film like the revamped office, The Chad's tugboat, the redneck bar, and this mysterious birthday party that Cameron even filmed a scene for. Not sure what that scene was about. Prinicpal photography began in January 2000 and production wrapped in June 2000. The film premiered in November 2000 and the rest is heavenly history. https://www.cinema.com/articles/168/charlies-angels-production-notes.phtml
