The Upside Down came to the U.K.! Netflix hosted a massive special screening of the first two episodes of Stranger Things Season 5 at the BFI Southbank in London Thursday night (November 13, 2025), and the entire core cast showed up looking like absolute royalty on the red carpet. From babies to bona-fide superstars in less than a decade — swipe right and try not to cry.

Millie Bobby Brown (21) — serving full bombshell in custom Louis Vuitton black velvet gown with a 10-foot train, shaved head long gone, now with waist-length blonde waves. Engaged to Jake Bongiovi and fresh off Damsel 2, she told reporters: “This is goodbye to my childhood — I’m sobbing already.”

Finn Wolfhard (22) — all grown up in a tailored Gucci suit with slicked-back hair and a five-o’clock shadow. He brought his band Calpurnia as his plus-one and joked: “I still flinch every time someone says ‘friends don’t lie.’”

Gaten Matarazzo (23) — rocking a deep emerald velvet blazer and matching teeth gems (Dustin would approve). He revealed Season 5 has “the biggest Dustin episode ever.”

Caleb McLaughlin (24) — pure fire in Balenciaga leather trench and boots, looking like he walked straight off a runway. Lucas fans are already screaming about his arc: “No spoilers, but I finally get the hero moment.”

Noah Schnapp (21) — clean-shaven and glowing in Dior Men, arm-in-arm with his boyfriend. Will Byers stans are losing it over leaked set photos showing him with the bowl cut again.

Sadie Sink (23) — ethereal in blood-red Rodarte with crystal-embroidered flames. Max’s fate is still the internet’s biggest question mark, and she just smirked: “Episode 1 will break you.”

Joe Keery (33) — Steve Harrington in full dad mode, bringing his newborn with partner Maika Monroe. The mullet is back and bigger than ever.

Natalia Dyer (28) & Charlie Heaton (31) — Nancy and Jonathan walked the carpet together in matching vintage Chanel, finally confirming they’re engaged with a massive diamond on Natalia’s finger.

David Harbour (50) — Hopper showed up in a kilt (yes, really) with Lily Allen, who wore a Demogorgon-inspired red latex dress. “One last time, kids,” he roared while hugging everyone.

Winona Ryder (54) — Joyce Byers looked timeless in Alaïa black silk, tears already in her eyes. She whispered to Millie: “You were 11 when we started… look at you now.”

Maya Hawke (27) — Robin slayed in a rainbow sequin suit, hinting her character gets “the gayest season yet.”

Priah Ferguson (19) — Erica Sinclair is all grown up in custom Marc Jacobs, taller than half the boys now and serving attitude.

The vibe was pure love and nostalgia. The Duffer Brothers teased: “Season 5 is our Empire Strikes Back — darkest, longest, most emotional. Bring tissues.”

Fans outside the venue were screaming so loud security had to add extra barriers. One viral clip shows Millie and Sadie hugging for a full minute while crying.

Filming wrapped in Atlanta last week after 978 days of production. Final season drops in three parts: Part 1 — July 4, 2026 Part 2 — July 31, 2026 Part 3 (finale) — November 11, 2026 (exactly 10 years after Season 1 premiered).

This London red carpet wasn’t just a premiere — it was the beginning of the end. Stranger Things forever.
