Many creators creating Youtube videos and other art forms approach me with a query whether they can copy a particular scene from a movie for mimicry, criticism, or creating a derivative art form, etc. And if they can copy how much can they copy, how long that particular scene can be. Though there does not exist any straightjacket formula for these questions. This is dealt with by the Doctrine of Fair Use/ Fair dealing, and the usage of whether permissible or impermissible would depend on case to case basis. This judgment beautifully captures the essence of fair use.
