The cast of Netflix's Stranger Things won at the SAG Awards Sunday night, and one cast member in particular stole the show.

Stranger Things won the award for Outstanding Performance by an Ensemble in a Drama Series at the SAG Awards, defeating the likes of Netflix's The Crown, PBS's Downton Abbey and HBO's Game of Thrones and Westworld. David Harbour, who plays Jim Hopper on the sci-fi drama, accepted on behalf of the very excited cast and delivered a rallying cry about helping to protect the disenfranchised.

However, it was difficult to focus on Harbour's speech because of the facial reactions of who was standing next to him: Winona Ryder. The actress, who plays Joyce Byers, gave what can only be described as a master class in facial expressions as she reacted to each part of Harbour's speech.

Ryder has mostly stayed out of the spotlight for several years now, with Stranger Things being her big comeback. The show has turned into an unexpected phenomenon since debuting on Netflix this past July, with viewers immediately falling in love with the cast of great young actors Millie Bobby Brown, Finn Wolfhard, Gaten Matarazzo and Caleb McLaughlin. Ryder's performance as a grieving mother desperate to find her son has also been acclaimed, netting Golden Globe and SAG Award nominations.

Stranger Things is also becoming an awards juggernaut. While the show did not win any Golden Globes, it picked up the Producers Guild of America Award for Drama Series and now it has the SAG Award for Best Drama Ensemble. If the Netflix series is able to carry its buzz all the way through Emmy season, it could pull in a huge haul in September.

Stranger Things is expected to return for season 2 sometime this year, though Netflix has not announced a specific release date.
