“The studios are not in the movie business anymore,” director-producer John Landis recently said during the Mar del Plata Film Festival, which I attended a few years ago. “Some of us were very lucky. I started to make movies for the studios in the ’70s. They were dying, but at least they were still studios. There are no original ideas. What there is — and this is something no one understands — is that it is never about the idea, it is about the execution of the idea.” Exactly. The monster-on-the-loose idea behind Landis’s Schlock (’72) was nothing special, but Landis used an exploitation concept to deliver dry social satire. It was as amusing in its way as Attack The Block (which made hilarious use of blatantly fake-looking aliens) was in its own.
