The theater is filling up fast. Only a few days ago, we reported that the new host for the Mystery Science Theater 3000 reboot will be comedian Jonah Ray. Now, it has been confirmed that Felicia Day will be the new mad scientist.

She will be playing a new character, Kinga Forrester, who is the sister of original chief mad scientist Dr. Clayton Forrester and the daughter of Pearl Forrester.

The news comes about two weeks after series creator Joel Hodgson started a Kickstarter campaign to bring the cult favorite show back. The original series was cancelled in 1997. Within six days, the campaign reached its $2 million goal.

On Twitter, Day shared the exciting news and promised to “terrorize the hell outta Jonah Ray.”

In addition to Day, Hodgson announced comedians Hampton Yount and Baron Vaughn will voice the new Crow and Tom Servo, respectively.

No word on when the new series will premiere.

From Hodgson, about casting Felicia Day:

I don’t remember where I first saw Felicia, but I remember knowing right away that there was something really interesting about her: both the way she looked and the way she behaved. She was beautiful, and yet, so capable of being character-y too: I suppose that makes her “adorkable.” Anyway, I checked out her seminal webseries, The Guild, and was just delighted. She was like a geek Mary Richards from The Mary Tyler Moore Show! And then I saw her in Dr. Horrible, and again, I was just so impressed.”
