WandaVision Creator Comes Clean About Quicksilver and Mr. Fantastic Fake Outs WandaVision Creator Comes Clean About Quicksilver and Mr. Fantastic Fake Outs WandaVision creator Jac Schaeffer comes clean about those Quicksilver and Mr. Fantastic clues in the show. Watching WandaVision has been a real test of patience for MCU fans. Every episode seemed to hint at the arrival of a major Marvel Comics character, from Magneto to Mephisto. One character whose arrival seemed practically a guarantee was Quicksilver from Fox's X-Men films, played by Evan Peters. But even though Peters did show up as the speedster, it was finally revealed that the character was a red-herring, an ordinary guy who had been hypnotized by Agatha Harkness. In an interview with Screenrant, the creator and head writer of the show, Jac Schaeffer confirmed that had been the plan for Peters' character all along.
