Cinematographer Gabriel Kosuth wrote an article for Variety which outlined his criticisms while carefully distancing himself from the movie, but Schrader, Cage, and others went for an even more subtle tactic. They went on social media, taking selfies of themselves wearing T-shirts printed with text from the non-disparagement agreement:
Good luck fitting that onto a Crazy Cage meme.
Granted, the stunt is useless for any viewer unaware of the context. Or anyone who saw Cage and thought, "Yep, that's totally something Nic Cage would wear. Those are probably words he thinks a talking goat whispered to him on the set of Ghost Rider." Still, it's a pretty clever way to say, "My contract forbids me from saying anything bad about this movie, therefore I am forced to say nothing."
