[I]t's basically like Aliens. But whenever I spoke to Cleve [Nettles, the writer], Cleve had a high concept, you know: It's ... sort of like if Tarantino wrote Gremlins. ... I was like, 'It's exactly it.' ... It's one of the things where the comedy is really pure, but the scares and the threats are all very real.
One of the producers, Chris Patton, he calls me up and he says, ... 'I've got a lead on a guy who can train Rhesus monkeys.' ... [They] like to hold prop guns and wear helmets and stuff. And so there's going to be a mix of live [and puppets]. I'm a real big fan of prosthetics, sort of puppets and stuff, and we'll probably have a little bit of CGI, you know, like for whenever it makes sense and stuff. But I would love to do things sort of as practical as possible with it.
