Hello all, this is my first post but I've been reading almost non-stop since I joined. I know the question has been asked many times over if adaptation without permission is okay (which it is not I understand), however I only want to do this for personal purposes. I am a new filmaker and this will be my first film. I'm wanting to adapt Douglas Hill's "Heart In The Ground" into an eight minute film, and do not plan on trying to sell or market it. I don't even want to enter it into any festivals, I just want to get going with my film making and thought starting with one-act plays would be a good place to start gaining experience with. So if I'm adapting my own screenplays from other peoples' plays but not making any money off of them, am I safe from infringment? I don't even see how I could be sued since I won't be showing it publicly.
