“Big Brother” fans, get ready for all-new houseguests and innovative twists when Season 20 debuts this summer. “It’s gonna be a big season,” producer Allison Grodner recently revealed to Gold Derby about the upcoming 20th season of CBS’s reality TV competition. “We have a lot planned for this season.”

For a show that loves to mix things up by casting returning favorites (like Paul Abrahamian last summer) alongside newbies, Grodner confirmed that won’t be the case this year. “I think there’s certain expectations from our fans that it’ll be an all-stars season and all of that, and I think we’ve pretty much put that to rest,” she told us. “This will be a brand new cast.”

As for the current status of Season 20, Grodner explained, “We are in casting right now. We are really excited about completely revamping this house. Wait till you see it — it’s a whole new thing, it’s spectacular. We are excited about some really new and innovative twists that will help commemorate this 20th season.”

One thing the 20th cycle won’t be is another celebrity version. After this winter’s successful celeb edition, which will be eligible at the Emmys, “Big Brother” is going back to casting everyday people for the 2018 summer installment. Marissa Jaret Winokur ended up winning the first-ever U.S. celebrity season, while Omarosa stole much of the headlines for spilling secrets about her time in the White House.

However, we haven’t seen the last of “Celebrity Big Brother.” In fact, Grodner is already considering how to fix the problem of celebrities like Keshia Knight Pulliam and Metta World Peace throwing in the towel. “The quitting element is something we’re going to look at,” Grodner confessed. “What can we do so that people aren’t asking on a regular basis to be voted out? I think we need to make sure that they’re committing to this fully and that if they really can’t handle it and need to quit, that we figure out another way of doing it.”

The last five regular editions of “Big Brother” all debuted in the last week of June, which suggests the Season 20 premiere is less than two months away. The 16 or more houseguests will be filmed 24/7 for our viewing pleasure, and they’ll be completely cut off from the rest of the world for approximately three months.
