Hey everyone. I have put together a production guide for the classic "Charlie's Angels" series.

Do the script dates represent the final completed drafts for each of the episodes, before shooting could begin on them?

Most of those dates I got were from the DeForest Script collection from the Online Archive of California. Some dates were from the Scriptcity.com website. I even looked up some corbisimage photos from the production of the episodes. It's also amazing that some episode scripts were written but never produced (There was quite a number of them) and some episodes weren't even listed by their aired title name but under different titles. (ex: "Pretty Angels All in a Row" was titled "Along came a Spider") Until I have all of the correct inofrmation verified, this is the episode information I have. I might have to go back over them and do some more research but if you or anyone else knows anything, please feel free to contribute.

hch, a bit late here, but you're missing the pilot that pre-dated the inaugural season. It was filmed in July of 1975.
