Check Out Unseen 'Full House' Photo Of John Stamos, Elizabeth Olsen Ahead Of 'WandaVision' Finale

John Stamos took "Full House" fans on a trip down memory lane by sharing an unseen photo of himself with Elizabeth Olsen.

Ahead of the finale of Olsen's "WandaVision" Friday, Stamos posted a throwback photo with the actress from the set of "Full House," which ran from 1987 to 1995. In the Instagram photo that was taken when Olsen was around 6 years old, the actor can be seen smiling and giving her a hug.

"One day she’s a little girl wandering the set, and next thing you know, she’s taking over a whole town, mindcontrolling the citizens to play out her favorite TV Sitcoms! They grow up so fast...," the actor captioned the snap.

Jodie Sweetin, who played Stephanie Tanner in the sitcom, commented, "Love this!!!"

In 1995, Olsen made a special appearance as "Girl with Flowers" in an episode of the show, which starred her sisters Mary-Kate and Ashley Olsen.

As for her Marvel character, Olsen's role is popular among superhero fans, but the actress recently revealed that her mother has been calling her "WandaVision" character the incorrect name.

She plays Wanda Maximoff, a.k.a. the Scarlet Witch, in the Disney Plus series. She has been suiting up and getting into superhero mode since 2014’s "Captain America: The Winter Soldier."

During an appearance on Jimmy Fallon’s talk show, the actress said, "My mom just told me the other day that she’s been calling me the Red Witch for the last – she said four years, but I think I’ve been doing this for like six or seven. She just learned that I was called the Scarlet Witch last week."

Surprisingly, Olsen never corrected her mother. "I told her, ‘I just thought you were making a joke. I didn’t know that’s what you thought my name was!'" she shared.

Olsen will return as the Scarlet Witch in the upcoming movie, "Doctor Strange in the Multiverse of Madness," which is set to premiere in March 2022.

Meanwhile, Marvel Boss Kevin Feige said that as of now, there are no plans for "WandaVision" Season 2, Deadline reported.

“I’ve been at Marvel too long to say a definite ‘No’ to anything as far as a second season of 'WandaVision,'” said Feige.

“Lizzie Olsen will go from 'WandaVision' to the 'Doctor Strange' film,” he added.
