I link to scripts that I find on the Internet. I like to reading scripts. I particularly like to read early drafts of scripts. It is amazing how the story changes from an early draft to a final shooting script to the final movie. Your script is waaay different from the movie.
Scripts change between early drafts and final shooting scripts.
Many times, one scriptwriter will write a draft of a script, then it goes to other script writers who make changes. Still later, when the final film is put together, the editor or director may decide to cut some scenes they feel are not important to the story. I see you calling some things scripts or screenplays or transcripts or close captioned transcripts. A Script or Screenplay is the plan for the movie. Sometimes plans change, hence the script you read is sometimes different from the final movie.
