Rob Savage's horror film 'Host' had only a 17-page script Adv. Filmmaker Rob Savage says his horror film “Host” only had had a 17-page outline script. “I don’t know how much these guys have gone over, but yeah. We had, I think it was a 17-page outline, so every day I’d kind of turn up on Zoom with the actors, and we’d have a short paragraph to describe the scene. The actors and I would basically have to rehearse it and do take after take, and try to find what was working and what wasn’t,” Savage said.
