Do I need to get friends or potential crew members to sign some sort of release when I talk to them about the film I am working on? I think I heard somewhere that even if a friend makes a suggestion or helps out in some way like loans me a piece of gear, that they can claim some sort of rights to the film. I found the 588 forms website but am not sure which one I need. Something combined with an NDA would be ideal. Sorry if this has been answered 100's of times, Google wasn't helpful.
