Yep, Facebook is joining the streaming craze. They just gave a 10 episode straight-to-series order to "Avengers" star Elizabeth Olsen's half-hour drama/comedy, which is still untitled at this point. The Scarlet Witch actress will both star and executive produce the series, which will run on the streaming platform Facebook Watch.

The series was created and written by Kit Steinkellner, and Deadline said it's among the first high-end series ordered by Facebook as it makes the push into premium original content. The series was originally set up at Showtime before moving to Facebook.

Apparently the synopsis is still a bit of a mystery, but Olsen is reportedly playing a young widow dealing with grief while reconnecting with relationships from her past. (Deadline added that YouTube Red has a similarly themed half-hour pilot, "Widow.")

When she's not fighting alongside the Avengers, Olsen has earned raves for her performances in films like "Martha Marcy May Marlene" and "Wind River." She shared a statement on the series pick-up at Facebook Watch:

"I couldn't be prouder of the group we have brought together for this show. Kit's story has been near and dear to me for years and I can't wait to share our dark, funny, and complicated show with the world."

Olsen will next be seen in the superhero mosh pit "Avengers: Infinity War," opening May 4.
