It was a red-hot red carpet at the Screen Actors Guild Awards 2017 Sunday as some of Hollywood’s biggest stars faced 80-degree temperatures while hoping for a big win. Many did not go home disappointed.

From happy post-victory celebrations to red carpet reunions, here are all the moments you didn’t see televised.

On the red carpet:

As the one-year anniversary of Downton Abbey‘s final episode approaches, the cast already seems to be getting nostalgic. Michelle Dockery was all smiles while greeting friends and hanging out with Laura Carmichael before having a sweet reunion with Lesley Nicol.

Elsewhere, Orange Is the New Black‘s Dascha Polanco – who donned an all-black jumpsuit – ducked into the PEOPLE and Entertainment Weekly red carpet corner to catch a little breeze.

“I don’t wanna look a mess for the carpet, honey!” she joked.

Polanco’s OITNB costar Taylor Schilling was busy gushing over Lion star (and best supporting actor nominee) Dev Patel, exclaiming, “nice to meet you.”

Schilling also mingled with Hidden Figures actress Janelle Monáe, who stopped to introduce herself, calling the star “sweetie.”

The carpet wasn’t short on PDA from its hottest couples, like John Legend and Chrissy Teigen. Legend couldn’t help but playfully grab his wife’s bum while they waited to do interviews. Later, the model prodded Blackish‘s young star Miles Brown to come on Lip Sync Battle.

Brie Larson arrived arm in arm with her fiancé, Alex Greenwald, and John Krasinski stood by patiently as wife (and nominee) Emily Blunt posed for solo shots.

Happy couple Joe Manganiello and Sofia Vergara worked to make each other laugh with goofy faces in between interviews.

Westworld star Thandie Newton seemed thrilled to run into best actor nominee Casey Affleck, who was making the star laugh animatedly. Later, Newton affectionately hugged and kissed Rami Malek, before introducing him to her husband.

Michelle Williams was quick to acknowledge her screaming fans, breaking off to give autographs to the sign-toting Manchester By the Sea enthusiasts. Best pal and always-date Busy Phillips stood nearby.

And, pleasing everyone, Barb continued her return from the dead. Stranger Things castmates Natalia Dyer and Shannon Purser hugged and posed for a happy red carpet photo before the series’ big win.

Inside the ceremony:

As the night’s trophies were handed out, the big winners gathered backstage.

Thrilled Schilling declared “This is insane!” as she and the women of OITNB celebrated their comedy assemble win.

The room was packed as the cast hugged and kissed, and, of course, drank champagne.

Sarah Paulson stressed while doing press after her outstanding performance by a female actor in a television movie or limited series win, exclaiming, “I’m missing Dolly [Parton’s speech]! This is terrible.”

The Crown star Claire Foy nearly missed her own big moment when faced with an enormously long bathroom line.

Luckily, a few women let her skip ahead as The Crown’s categories approached. Afterwards, she and her girlfriends – laughing and giggling – rushed out of the bathroom to head back to their seats, just in time to see co-star John Lithgow win.

Foy also struggled to grasp that she was on with her acting idols — who are now her “peers.”

“[It’s] really, really bizarre!” she said. “Denzel Washington is now my peer?! I mean, not, obviously, but we both won one, so we sort of are…?”

During a commercial break, the excited Hidden Figures cast posed for a photo and noticed their seemingly shy castmate Kirsten Dunst lingering nearby. The cast – who won the night’s top honor – immediately stopped taking the photo, insisting she join.

“Come hereee!” they requested.

Taraji P. Henson may have given a politically-driven acceptance speech, but she tells PEOPLE she has no plans to make a run for the White House in 2020.

“Noooooo! I don’t want to get all grey and wrinkled!” she joked.

While many stars emptied into the after-show gala shortly following the event’s close, Blunt, Krasinski and Affleck lingered in the cleared out floor-level ballroom chatting.

At the after-parties:

Blunt introduced teen Game of Thrones star Maisie Williams if she’d met her husband, and when the actress tapped Krasinski’s shoulder, he flipped out that he was meeting Arya. “Oh! I love you!” he gushed.

Kate Hudson got her coffee fix on her way out, grabbing two Dunkin’ Donuts coffees.

Henson, Dunst, Janelle Monae and the rest of Hidden Figures cast were inseparable to the point where they all crammed into one booth taking photos and chatting.

Manchester by the Sea star Lucas Hedges made sure to chat up and snap a few pics with Stranger Things costars Joe Keery and Natalia Dyer.

At the Weinstein Company and Netflix’s after party (where the stars sipped on Absolut Elyx and Heineken beer) held at Sunset Tower, cute couple Chrissy Teigen and John Legend continued showing off some adorable PDA. “They were the nicest people ever, chatting with the kids from Stranger Things and dancing to Sean Paul’s ‘Get Busy’ as well as a number of ’90s throwback jams,” says an onlooker. After working up an appetite at the bash — presented by Audi — Teigen snacked on a mini cheeseburger.

Winner Millie Bobby Brown — along with her cast — started a dance-off with the Orange cast, and Rami Malek was seen chatting with the kids and offering his phone number in case they ever needed advice, adds the onlooker.

Changing into a different dress, Kerry Washington was spotted chatting with Laverne Cox about makeup, their favorite shows and how Cox is a huge fan of Scandal. “She was ready to relax and enjoy the party with her husband,” says the onlooker.
