Will Jason Isaacs ("Hap") and the other cast members come back?
Though it was centered around Prairie's journey of self-discovery, The OA had a large cast with numerous subplots. It makes sense that fans are hoping the show will provide some new adventures for the high school characters Steve, Jesse, Buck, French, and their teacher BBA. And what about the evil Dr. Hap? You can't have The OA without Dr. Hap, right?
There's very little concrete casting info online about who will be back for Season 2. But thanks to Jason Isaacs taking to social media, we do know that the Star Trek: Discovery actor will return, sharing that he finished filming his scenes in early May of last year.
Brooklyn singer-songwriter Sharon Van Etten, who played one of Dr. Hap's captives named Rachel, will also appear again. When speaking to The New York Times about her recent album, the recording artist also briefly spoke about her work on the series -- without revealing any details about the new season, of course. But, she will be back!
As for the younger actors in the cast, Brandon Perea, who played "French" in Season 1, did tweet some photos of him hanging out with his fellow cast members Ian Alexander, Brendan Meyer, and Patrick Gibson. While at first it was unclear if they were just hangin' or were taking a break from shooting scenes for Season 2, one can assume they'll be back, as they appear in the recent trailer.
