Here's The "Stranger Things" Cast In Their First Big Role Vs. In The Movie Vs. In Real Life

Stranger Things is back, baby! And it's truly one of the most chaotic seasons yet.

Now, six months after the Battle of Starcourt, the gang will return to take on their biggest threat yet: high school. Hopper is still missing, the Byers family moved away, and Eleven is still struggling without her powers. Oh, and there's the Upside Down, of course. With a new villain on our hands, we'll watch as our favorite characters put an end to the Upside Down once and for all.

So, to celebrate Stranger Things' fourth season, below are some photos of the cast in their first big role vs. in the series vs. IRL:
