Randall Park says he trained with a magician to pull off the Jimmy Woo card trick in 'WandaVision'

• Randall Park told Insider he spent days learning the Jimmy Woo card trick in "WandaVision" for real.
• The card trick is a callback to 2018's "Ant-Man and the Wasp."
• "Actually, a magician taught me that," Park told Insider.

Episode 4 of "WandaVision" was a major payoff for fans as it cleared up a lot of questions that have been hanging over the series to this point. And on top of that, Jimmy Woo is back in the MCU.

The FBI agent who chased around Scott Lang in 2018's "Ant-Man and the Wasp" appears on the show as he's investigating a missing person's case at Westview, New Jersey, which is now under the control of Scarlet Witch (Elizabeth Olsen).

To reveal the character, Woo, played by Randall Park, introduces himself to S.W.O.R.D. agent Monica Rameau (Teyonah Parris) by doing a card trick to give her his business card.

Fans will recognize that as a hat tip to "Ant-Man and the Wasp," during which we saw Woo try to learn how to do the card tricks Lang had shown him.

It turns out that quick sleight of hand move was actually pulled off by Park, it wasn't some CGI trickery.

"No, that was me," Park revealed to Insider. "Actually, a magician taught me that and I worked really hard on it before that scene because I had to get it right."

So, did it take him weeks to get the move right?

"Really a couple of days," Park said. "It's actually not as difficult as it seems."

Park said the card trick was something that was always in the script, which he thought was a fantastic way to reintroduce audiences to Jimmy Woo.

"Marvel, you know, they make all the connections, so that was in there," he said. "When I read it, I was really happy to see it."

"WandaVision" is available on Disney Plus.
