Actress Elizabeth Olsen says she was clueless about Marvel's plans to create a multiverse until she was approached to be part of Doctor Strange In The Multiverse Of Madness. Olsen's Marvel outing "WandaVision'' had Evan Peter's arrival as fake Pietro. Both the characters -- Wanda and Evan -- had been introduced by Marvel in the "Avengers" franchise. However, Olsen at that stage wasn't aware of the Marvel bosses' plans to start a Marvel multiverse.

After finishing her post-production work for WandaVision, Elizabeth, who played the role of Wanda Maximoff in Marvel's "Avengers" franchise, moved to London for the "Doctor Strange" sequel starring Benedict Cumberbatch.
