For her role as Wanda Maximoff in WandaVision, Elizabeth Olsen completely immersed herself in period sitcoms so she could nail the physicality of each era. However, there was just one trick she couldn't pull off: Elizabeth Montgomery's iconic nose wiggle from Bewitched.

"Well, I can't wiggle my nose, so we had to figure out something else that was period appropriate," Olsen recalled with a laugh. "So this kind of [finger pointing] was our translation and to watch our special effects team that usually blow things up, set things on fire, create wind, create smoke -- these guys became like puppeteers of things floating in the sky and dealing with magnets in different ways, to make things spin, and it was just so incredible to watch our special effects team adapt to the era of specific ways of creating these practical effects by doing the research of what did they do on Bewitched. Or even as stupid as holding still and doing a quick change and trying to remember your body for the camera. There's just a lot of silly things that we got to do that I'm used to it all just coming together in CGI. So it was really fun to have the practical effects there."

In lieu of a nose wiggle, Olsen's Wanda makes a hand gesture instead: a simple, but clear finger point. She used this often in the series' second episode, when her talent show performance with Vision went awry and she had to quickly explain away some of his wild feats. Of course, Vision's stunts wouldn't have been possible without the special effects team, who used tricks from the beloved Bewitched sitcom to contribute to era-appropriate look of the episode.

Disney+'s WandaVision takes place following the events of Avengers: Endgame, which saw Earth's Mightiest Heroes reverse Thanos' Infinity War snap and bring back half of all life in the universe. In the wake of that, Wanda Maximoff, aka the Scarlet Witch, has found herself in a bizarre reality where her life is a sitcom. However, something insidious lurks beneath the surface of this picture-perfect world, and that may spell trouble for more than just Wanda and Vision.

Written by Jac Schaeffer and directed by Matt Shakman, WandaVision stars Elizabeth Olsen as Wanda Maximoff/Scarlet Witch, Paul Bettany as Vision, Randall Park as Agent Jimmy Woo, Kat Dennings as Darcy Lewis, Teyonah Parris as Monica Rambeau and Kathryn Hahn as Agnes. The series premiere is now available on Disney+.
