Please keep in mind: these free script websites might provide screenplays that are of poor quality or unreliable. So if you can find an officially published version of the script, that would be preferable. If you find an early script or early draft of a script, I would recommend that you not use it. You want the shooting script that was actually used to make the film in question. An early draft might differ greatly from the final, produced screenplay. Look for information that indicates whether you are reading an early draft of the script or the script that was used for the film.
