Breaking down phase 4 of the MCU in an exclusive interview with Rotten Tomatoes, Marvel Studio head Kevin Feige promised we haven’t seen the last of WandaVision‘s antagonist Agatha Harkness.

Masterfully played by actress Kathryn Hahn, Harkness was THE breakout character of WandaVision and captured fans imagination.

Rotten Tomatoes: Feige: “When Bob Iger told us about Disney+ and about his desire for us to produce shows for Disney+, it gave us a new avenue, frankly, to do something we hadn’t been considering before, which was really doing a deep dive on characters who deserve a deep dive but hadn’t had the chance yet.”

 It took us four or five films to tell even a tiny story of Wanda Maximoff and The Vision.

“BY THE FIRST FEW EPISODES OF WANDAVISION, PEOPLE ARE ASKING, ‘WHERE IS AGNES GOING TO SHOW UP AGAIN? WHAT ELSE IS SHE GOING TO DO?’… WITHIN THE MCU, [KATHRYN HAHN’S RETURN]  CAN’T COME SOON ENOUGH.”

“We were all fans of [Kathryn Hahn] at Marvel Studios. And she had come in for a general meeting coincidentally right around the time we were trying to cast Agnes-slash-Agatha. It was one of those, ‘Why didn’t we think of this before?’ Louis D’Esposito [co-president of Marvel Studios] actually sat down and had a general [meeting] with her. And it very quickly went from that: She’s great. What could she do for us someday? Anyway, who’s going to play Agatha? We really have to cast this part. Wait a second… It was honestly almost exactly like that.

One of the great things in building the MCU is seeing audiences respond to characters that they were not expecting or that they were not asking for. I wouldn’t say there was a huge contingency of people banging down the door for Agatha Harkness to appear in the MCU, but she’s a great character portrayed by a great actress. And by the first few episodes people are asking, ‘Where is she going to show up again? What else is she going to do?’

Asked when we will see Harkness next, Feige says some day. “Someday soon. You will see Kathryn Hahn in Knives Out 2 next, then maybe an assortment of other things. But within the MCU, it can’t come soon enough. Let’s put it that way.”
