Grab your trench coats, brew a fresh pot of English breakfast tea, and lock your flat doors because the Arconia’s favorite true-crime podcasters are packing their bags for Blighty!

In what is easily the most monumental casting coup of the television year, the undisputed queen of British acting, Dame Olivia Colman, has officially joined the mega-hit Hulu/Disney+ mystery-comedy series Only Murders in the Building for its incoming sixth season.

And if that wasn’t enough to send television fanatics into a flat-out frenzy, producers have confirmed that Season 6 will trade the bustling, sirens-filled streets of New York City for the foggy, historic alleys of London, England!

The jaw-dropping announcement dropped like an absolute bombshell on social media via a slick, star-studded Instagram video that immediately sent the internet into meltdown.

The teaser clip featured none other than trio mainstays Selena Gomez, comedy legend Martin Short, and Hollywood royalty Meryl Streep bantering in quintessential Only Murders fashion before revealing their ultimate, award-winning secret weapon: Miss Olivia Colman herself.

“We have had so many amazing guest stars for ‘Only Murders’ in London!” Selena Gomez beams into the camera lens, dripping in effortless chic.

“Yeah, but we’re just missing one!” adds Meryl Streep, flashing her trademark, dazzling smile, right before the camera pans to reveal a grinning Colman casually stepping into the frame.

Cue the collective gasps of millions of fans across the globe!

From the Arconia to Buckinghamshire: A Massive International Shift

For five incredible seasons, loyal viewers of the critically acclaimed whodunnit have grown deeply accustomed to the cozy, claustrophobic, and corpse-ridden confines of the Arconia, a posh Upper West Side apartment building hiding more dark secrets than a royal palace.

Charles-Haden Savage (Steve Martin), Oliver Putnam (Martin Short), and Mabel Mora (Selena Gomez) built their quirky true-crime podcast empire on the foundation of New York grit, Broadway drama, and local gossip.

However, shifting the backdrop entirely to London for Season 6 marks an unprecedented, thrilling pivot for the series. Could an unfortunate, grisly demise happen on British soil? Knowing this show’s uncanny knack for drawing homicide wherever they go, you can bet your bottom dollar that a hapless victim will be meeting a gruesome end somewhere near the River Thames.

Industry insiders whisper that the transatlantic relocation will allow the writers to inject fresh, fish-out-of-water comedy into the dynamic trio’s dynamic, as New York’s most chaotic podcasting sleuths attempt to navigate British etiquette, rainy weather, and suspicious aristocracy.

A Masterclass in Casting: Colman Meets Streep

Let’s take a collective moment to appreciate the sheer magnitude of the acting talent currently assembled on a single television set.

We are talking about an unprecedented collision of titans: Meryl Streep—the most nominated actress in Academy Award history—and Olivia Colman, Britain’s fiercely beloved national treasure who secured her own coveted Oscar for her unforgettable turn as Queen Anne in The Favourite.

Having Colman lock horns (or share a witty, dry-humored cuppa) with Meryl Streep is the kind of high-stakes television masterclass that fans only ever dream about in fanfiction.

While details surrounding Colman’s character are currently being kept tightly under wraps by Disney and Hulu executives, sources close to production tease that her role will be “pivotal,” deeply tied to the London leg of the mystery, and packed with the signature razor-sharp wit that Colman delivers effortlessly.

Will she play a shady British aristocrat with skeletons in her ancestral closet? A cynical Scotland Yard detective who refuses to take the American podcasters seriously? Or perhaps a fellow resident of a high-end London luxury estate where a fresh body has just dropped? Whatever the case, Hollywood’s elite are lining up to join the Arconia universe, and frankly, who can blame them?

The Internet Goes Wild Over the London Reveal

Naturally, social media wasted zero time erupting into utter chaos following the morning drop of the Instagram announcement.

X (formerly Twitter), TikTok, and Instagram were flooded within minutes by ecstatic fans sharing screenshots of Colman’s surprise entrance.

• “OLIVIA COLMAN AND MERYL STREEP IN THE SAME SHOW?! THIS IS NOT A DRILL! PROTECT THEM AT ALL COSTS!” one zealous fan tweeted in all caps.

• “Only Murders moving to London with Olivia Colman is literally the greatest cultural reset of 2026. Take all my money, Hulu,” wrote another.

• “Imagine being a fictional British person just minding your business and suddenly Martin Short, Selena Gomez, and Meryl Streep show up to investigate your murder. Iconic behavior,” chimed in a popular TikTok creator.

The crossover appeal of blending America’s favorite quirky sleuths with British royalty has instantly catapulted anticipation for Season 6 to astronomical heights.

A History of Star-Studded Lineups

Only Murders in the Building has carved out a legendary reputation for pulling off jaw-dropping guest star lineups. Over its five previous seasons, the show has played host to an incredible roster of entertainment royalty, including:

• Tina Fey

• Nathan Lane

• Cara Delevingne

• Paul Rudd

• Amy Ryan

• Matthew Broderick

• Jesse Williams

• Jane Lynch

• Eva Longoria

• Eugene Levy

Yet, landing Olivia Colman—fresh off a string of massive global film and television successes—cements the series as arguably the most prestigious comedy-drama gig on television today. Actors are actively begging showrunners to let them get murdered on this show, and it’s not hard to see why.

What Else Do We Know About Season 6?

While plot specifics are being guarded like state secrets in an MI6 vault, creators John Hoffman and Steve Martin have hinted that Season 6 will structurally expand the show’s universe wider than ever before.

With Mabel, Charles, and Oliver taking their microphone overseas, production is expected to kick off major filming blocks on location in the UK, utilizing iconic London backdrops, historic theatres, and posh West End flats.

Will local British sleuths join forces with our trio? Will Charles finally master the art of drinking proper English tea without spilling it on his trench coat? And most importantly, who is going to end up face-down in a puddle of Earl Grey?

As production ramps up across the pond, one thing is abundantly clear: Only Murders in the Building Season 6 is shaping up to be the absolute must-watch television event of the year.
