"Well, when they first said, 'We want to bring Jimmy back,' I was like, 'I'm in. No questions asked. I don't care what it is,'" Park tells EW. "I'm gonna do it because I just love Marvel, and I had so much fun on Ant-Man and the Wasp. Then when they broke down the show, I was even more excited. I did not expect anything like this, so I was very thrilled to be a part of it. But (I was) also wondering a little bit how they would pull it off because it is such a big swing, you know? But they did it. It's just so incredible to watch." ALSO: Park talks mastering Jimmy Woo's card trick.
