Big Brother has long been a summer staple for fans of American reality television. Though it stumbled out of the gate with a poorly received first season, a major format change—from the U.K.-inspired audience voting to a Survivor-style system where houseguests vote each other out—breathed new life into the series. Since then, it has become a cornerstone of CBS’s summer programming.
Now entering its 27th season (not including spin-offs like Over the Top, Celebrity Big Brother, and Reindeer Games), the show remains a powerhouse. Its iconic motto, “Expect the unexpected,” continues to define the series. While some twists have fallen flat, others have delivered explosive drama, chaos, and unforgettable moments of reality TV gold.
This year, the producers are promoting Big Brother as the most unpredictable season yet. While we’ve heard similar promises before, the question remains—will this season truly deliver jaw-dropping twists?

The show’s iconic slogan, “Expect the unexpected,” is once again front and center—but this time, executive producers Allison Grodner and Rich Meehan seem to be leaning into it more literally. CBS and Julie Chen recently unveiled the season’s teaser artwork, featuring vintage-style master keys—the kind you’d find in an old mansion—hinting at a mysterious new theme.
“The key to a perfect summer is no mystery,” the EPs told Entertainment Weekly. “Get ready to unlock the most unexpected season of Big Brother yet!” As EW’s Dalton Ross noted, they’ve basically just told us to expect the unexpected—again.
There are 48 keys shown in the teaser, though it’s unclear whether that number holds any real significance. As for host Julie Chen Moonves, she’s keeping things cryptic.
“The keys to unlocking unexpected mysteries in the Big Brother house are right in front of you! Don’t be left in the dark this summer. Be sure to tune in!” she teased.
Not exactly the most revealing hint.
In truth, we still don’t know much. It’s obvious that keys play a central role this season, but the details—what they mean, how they’ll be used, and why—remain a mystery. One thing’s for sure: major twists are coming. Hopefully, they enhance the chaos and excitement without tipping the scales unfairly. If done right, these surprises could push houseguests to their limits while keeping the game intense and balanced. Only time will tell.
Big Brother has never been afraid to stir the pot with bold, controversial twists that challenge both the players and the game itself. While we’d love a bit more clarity about the role of these mysterious keys, the good news is we won’t have to wait much longer—Season 27 is just around the corner.
Mark your calendars: Big Brother premieres July 10 at 8 PM EST on CBS and Paramount+. For fans who can’t get enough, live feeds will be available on Paramount+ and Pluto TV. The main episodes will air on Wednesdays, Thursdays, and Sundays. Plus, a brand-new companion series, Big Brother: Unlocked, debuts July 25 and will stream Fridays on Paramount+ and Pluto TV, offering in-depth analysis and extra content for the ultimate superfans.
