As the highly anticipated Big Brother Season 27 approaches, excitement and speculation among fans are reaching a fever pitch. This summer, the iconic reality competition promises to deliver fresh drama, shocking surprises, and a few nostalgic nods to its past. With a confirmed premiere date, the return of host Julie Chen Moonves, and intriguing teasers about a mystery houseguest and possible returning competitions, here’s everything you need to know about what’s coming next in the Big Brother universe.
When Does Big Brother Season 27 Start?
Big Brother Season 27 is set to premiere on Wednesday, July 17, 2025, at 9 p.m. ET on CBS, marking the return of the long-running series to its familiar summer slot. The premiere will be a special 90-minute live move-in event, allowing viewers to watch the new houseguests enter the Big Brother house and immediately start navigating the game.
The show will continue with its classic multi-night format. Following the premiere, new episodes will air every Sunday, Wednesday, and Thursday, keeping fans engaged with competitions, ceremonies, and live evictions throughout the summer. The Thursday episodes will maintain the tradition of live eviction nights, which often deliver the most unpredictable and dramatic moments.
Julie Chen Moonves Returns as Host
Julie Chen Moonves, the face of Big Brother since its debut in 2000, returns once again to guide viewers through the upcoming season. Known for her calm but pointed commentary, Julie has become synonymous with the show's brand of reality TV intrigue and suspense. Her presence reassures fans that, no matter how many twists are introduced, the core essence of Big Brother remains intact: expect the unexpected.
In recent interviews, Julie hinted that this season will feature elements designed to surprise even the most dedicated fans. While she remained tight-lipped about specifics, her enthusiasm has fueled speculation that this season could blend classic strategies with bold new gameplay.
The Mysterious Houseguest: Who Could It Be?
One of the biggest teasers about Season 27 is the mention of a "polarizing mystery houseguest." While producers have not confirmed the identity, fans have already started speculating: could it be a controversial past contestant, a celebrity, or a figure known outside of Big Brother?
The idea of a mystery houseguest is not entirely new to the franchise. Previous seasons have introduced twists where former players returned, secret houseguests competed for a chance to re-enter the game, or new players were added mid-season to shake up existing alliances. What makes this twist particularly exciting is the description of the guest as “polarizing,” suggesting they might immediately stir strong reactions among houseguests and viewers alike.
Bringing in a controversial figure could dramatically impact early gameplay. Houseguests might have to decide whether to align with or target someone who carries a history or reputation that affects the dynamic of the entire house. This twist aligns perfectly with Big Brother's strategy of keeping houseguests—and audiences—off balance.
Possible Twists and Returning Competitions
Season 27 appears to be leaning into the show’s legacy while also refreshing its format. While producers haven’t announced all details, there’s speculation that certain competitions and twists from past seasons might return.
Some possibilities fans hope to see include:
-
Battle of the Block: A twist where two nominated pairs compete, and the winning pair removes themselves from the block, forcing the Head of Household to name replacement nominees.
-
Double or Triple Evictions: Special nights when multiple houseguests are sent packing in rapid succession, keeping everyone on edge.
-
America’s Vote: Bringing back fan interaction, where viewers can influence the game by awarding advantages, punishments, or even a special power.
-
Secret Powers: Hidden abilities like the "Coup d’Etat" or "Diamond Power of Veto" that can dramatically shift the game’s balance.
Classic competitions could also return, such as endurance challenges where contestants hang on for hours to secure Head of Household, or memory games that test how closely houseguests pay attention to events in the house.
Fans love these nods to previous seasons because they blend familiarity with unpredictability. Even veteran viewers can’t always guess how returning twists will influence a brand-new cast with unique strategies and personalities.
Why Season 27 Feels Fresh
One of the biggest challenges for a show running as long as Big Brother is staying fresh while staying true to its core concept. The producers seem aware of this and are using the combination of a mystery houseguest, possible retro twists, and an all-new cast to create a dynamic environment.
By describing the mystery guest as “polarizing,” the show hints that conflict and drama will arise organically, rather than being purely manufactured. At the same time, revisiting fan-favorite twists could attract long-time viewers while still surprising them.
Additionally, the cultural moment of reality TV is evolving. Audiences today look for authenticity, social strategy, and unexpected emotional depth, alongside the classic betrayals and blindsides. Big Brother Season 27 seems positioned to balance all of these elements.
What Makes Big Brother a Summer Staple
Part of Big Brother's enduring appeal is the way it creates a living, breathing drama in real time. Cameras watch houseguests 24/7, and live feeds give dedicated fans unprecedented access to unedited moments. This format makes each season unpredictable, as the game's social strategy emerges organically from real personalities clashing under pressure.
Beyond the game itself, Big Brother has built a community. Podcasts, social media debates, and fan theories keep the conversation alive between episodes. The reveal of each season’s theme, house design, and twists becomes an event in itself, turning summer into a ritual for fans.
What Fans Should Watch For
As the premiere approaches, here are a few things for viewers to keep an eye on:
-
Identity of the Mystery Houseguest: This reveal will likely be a turning point for the early game.
-
Premiere Move-In Episode: Live move-ins often set the tone for alliances and rivalries.
-
Return of Classic Twists: Watch for announcements on returning competitions or powers that could dramatically alter the game.
-
House Design & Theme: Each season’s theme influences competitions, décor, and sometimes even gameplay.
-
Early Gameplay: The first few evictions often define the season’s narrative and major alliances.
Final Thoughts
Big Brother Season 27 promises to be both nostalgic and innovative, drawing on what has kept the show popular for decades while adding fresh elements to keep even veteran viewers guessing. With the July 17 premiere date locked in, the return of Julie Chen Moonves, the mystery houseguest twist, and rumors of classic competitions making a comeback, fans have plenty to look forward to.
As always, the only guarantee with Big Brother is that you should expect the unexpected. Stay tuned, and get ready for a summer of blindsides, showmances, alliances, and the unpredictable drama that only Big Brother can deliver.
