The cast of Stranger Things brought the fun to the Screen Actors Guild Awards on Sunday night before they won one of the night's biggest categories. After partying together the night before, the hit show's younger cast — Millie Bobby Brown, Gaten Matarazzo, Noah Schnapp, Finn Wolfhard, and Caleb McLaughlin — all hit the red carpet in style. They were soon followed by older stars Natalia Dyer, Joe Keery, and Shannon Purser, who took some time for a few cute group photos. Leading lady Winona Ryder (who was looking very '90s It girl, we should note) flashed a few smiles, as did costars David Harbour and Matthew Modine. We have no doubt that they'll give their epic night at the Golden Globes a run for its money.
