After a whopping three-year hiatus, Stranger Things has returned to Netflix with (most of) season 4. The talented cast has been busy with other projects during the significant break and it’s exciting to see the wide variety of movies and TV shows they've starred in.

From Millie Bobby Brown’s venture into the spy drama genre with Enola Holmes to Joe Keery’s appearance in the science fiction Free Guy, it’s worth finding out what the actors were up to during the gap. Since Stranger Things 4 only runs for seven episodes — with two more dropping July 1 — fans can watch their other works while waiting for the rest of the season.

Winona Ryder has slowed down on her movie career ever since starring in Stranger Things, but the three-year gap allowed her to return to the big screen with The Cow. The thriller centers on Kath (Ryder), a woman searching for her boyfriend after he goes missing during a stay at a remote cabin.
