Well, to be clear, the actor didn’t seem to be behind this video— some internet person took upon themselves. I’m sure Heather knows the terms of the agreement she signed; if there was grounds for her to have legal remedy, I’m sure she would have perused them already. But that doesn’t stop an interested internet fan from complaining on her behalf.

Again, all this is a best guess based on my experiences in this field. I have never personally investigated the terms of licensing for the Blair Witch Project.
