Came across this page and I can't help loving them, annotated scripts - pages of screenplays that weren't "only" filmed - but a bit of the production process, a bit of the personality, stays fresh with these notes.
This one is from a Star Trek episode that was aired as "Spectre of the Gun" and the notes are by none other than "Bones" DeForest Kelley. The front page lists the scene numbers Doc McCoy was in and the name and phone number apparently were those of one of the stuntmen, named Bob Orrison.
