The CBS reality show "does lend itself for sure to a quarantine," says executive producer Allison Grodner." It is safe because of the cast and the crew being separate, but we still had to make sure that the cast going in and living together could be safe. So they are currently undergoing a sequester period, and undergoing multiple tests to make sure that they're completely and totally negative — COVID-free — before moving into the Big Brother house. And the crew, yes, we're separate, but to pull off three nights a week for three months straight — we’re a pretty substantial-sized crew. And so there is actually a lot more behind the scenes that needs to happen to make sure that everybody doing the show can be as safe as possible. And so there's a lot that went into this — actually an over 200-page document, a detailed document that had to be written up step by step, thinking through everything that could possibly go wrong to make sure that we could pull off what we do every summer safely. Look, we're so excited to do this, but it's very complicated and yet at the same time, we wouldn't have done it until we felt that it was in a place where we could do it safely."
