WandaVision has released a promo trailer during Sunday’s Emmy awards and fans are scratching their heads whether Kathryn Hahn is playing Agatha Harkness.

WandaVision stars two Avengers from the Marvel Cinematic Universe, Wanda Maximoff (Elizabeth Olsen) and Vision (Paul Bettany).

The Disney+ series released its first full trailer during the Emmy Awards on Sunday (September 20th) which shows Wanda and Vision in a completely different setup, leaving many of us confused, yet very intrigued at what’s to come.

During one point of the trailer, actress Kathryn Hahn makes an appearance which has left many Marvel fans wondering if she will be portraying Agatha Harkness on the series.

WandaVision: Trailer

The trailer for WandaVision opens up with a black-and-white recreation of an old sitcom that stars Wanda and Vision as a happily married couple.

But soon everything changes when they get questioned how they met and why they don’t have any children by guests they have invited over for a dinner.

The black-and-white setup turns into more colourful and contemporary scenes before things get complicated.

At some point before the end of the trailer, people are flying through portals, we see police officers getting involved and Kathryn Hahn makes a few appearances too.

Kathryn features several times during the promo trailer. First, she appears in a black and white scene, then in an ’80s sports outfit and finally, she has a short conversation with Vision.

Kathryn’s character has been teased as a “nosy neighbour”, but we believe she’s there for much more since she is one of the main cast members on the series.

The final time we see Kathryn’s character, she is sitting in a car, dressed in what appears to be a Halloween outfit and a pointy hat.

She looks at Vision and asks: “Am I dead?” to which Vision responds: “No, why would you think that?”

“Because you are,” Kathryn’s character responds, leaving Vision baffled over her answer.

Many fans have speculated that Kathryn might play Agatha Harkness, though her character’s name is not listed on IMDB as of the time of writing.

Earlier this summer, set photos went viral which suggested that Kathryn could appear as Agatha after eagle-eyed Reddit fans shared snaps of the actress dressed in a medieval-style costume.
