We always knew X-Men franchise. The surprise casting has inspired all kinds of theories, but did you catch a bonus X-Men reference in WandaVision? In the â90s-themed sixth episode of WandaVision titled âAll-New Halloween Spooktacular,â the cast dresses up in their classic comic book costumes to trick-or-treat. Evan Petersâ Pietro rocked Quicksilverâs classic blue suit, with a bit more volume in his hair than youâd expect from the Marvel hero. WandaVisionâs hairstylist Karen Bartek confirmed that it was partially meant as a direct reference to Wolverineâs look during an interview with IndieWire, saying, It was something that Matt really [wanted]. They kind of planned that.
