Elizabeth Olsen downplays rumor that sisters Mary Kate and Ashley will appear in 'WandaVision'
"That would be incredible. It is very meta, the whole thing."
Elizabeth Olsen is staying silent on whether or not her older sisters, twins Mary Kate and Ashley Olsen, will make a cameo on her upcoming Disney+ series, "WandaVision."
During a recent "Jimmy Kimmel Live!" appearance, the Marvel star was grilled on several fan theories about her upcoming series.
A trailer for the show depicts Olsen's character, Wanda Maximoff (aka Scarlet Witch), trapped in a series of television sitcoms -- which has fans hoping that will open the door to allow Marvel to parody "Full House," the sitcom Olsen's older sisters starred on for eight seasons between 1987 to 1995.
"What about this one? Wanda bears a striking resemblance to these actors," host Jimmy Kimmel quipped while holding up a photo of the famous twins and hoped out loud that "Uncle Joey is about to join the MCU."
Olsen, 31, had a hard time keeping a straight face after hearing the fan theory and joked, "That would be incredible. It is very meta, the whole thing."
Kimmel tried his best to pry information out of the actress, such as confirming that the upcoming series is based off the popular "House of M" storyline from Marvel Comics that takes place when Wanda has a mental breakdown and tears a hole in the fabric of reality, throwing everyone into several alternate universes. The series ran for eight issues in 2005.
However, Olsen refused to give him a straight answer and encouraged everyone to watch "WandaVision" when it premieres on Disney+ on Jan. 15.
Marvel is owned by Disney, the parent company of "Good Morning America" and ABC News.
