'Cruella' star Paul Walter Hauser was surprised by his 'Falcon and the Winter Soldier' Easter egg

• Hauser says it was a "funny surprise" to learn Stan made him an Easter egg on the Disney Plus show.
• "I did not expect that," he told Insider.
• Hauser said he and Stan are "actively" looking for a project so they can work together again.

If you kept a close eye on Bucky Barnes' notebook in the first episode of "The Falcon and the Winter Soldier," that premiered earlier this year, you might have noticed a familiar name.

The book contained a list of people Sebastian Stan's Marvel character must make amends with after wronging them.

The second name on the list is "P.W. Hauser." That's a shout out to Stan's good friend and fellow actor Paul Walter Hauser.

In a recent interview with Insider, Hauser, who can currently be seen playing the scene-stealing Horace in "Cruella," reacted to being an Easter egg on the Disney Plus show, streaming now.

"It was a very funny surprise," Hauser said. "I did not expect that."

The actor said he called up Stan after seeing it and they both had a good laugh.

The two have been close since starring in the acclaimed 2017 movie "I, Tonya," which focused on the rise and fall of infamous figure skater Tonya Harding (played by Margot Robbie).

Stan played Harding's husband Jeff Gillooly and Hauser delivered a breakout performance as Gillooly's bumbling friend and later Harding's bodyguard, Shawn Eckardt. Harding, Gillooly, and Eckardt were connected to the 1994 attack on Harding's figure skating rival Nancy Kerrigan.

Hauser says since the two worked together, they have been looking for another project to team up on.

"We really want to do something together again, and it seems people out there want us to also," Hauser said. "We're spoiled though. We don't want to do anything else than something on the level of 'I, Tonya.'"

"We're looking at scripts. We're talking to our agents. We're both in with the same agency so we are telling them to find us a biopic or dark comedy where we can be the co-leads," he added.

Until that day comes, both actors are staying busy on other projects.

Stan is currently filming the upcoming Hulu series "Pam & Tommy," in which he plays rocker Tommy Lee opposite Lily James as Lee's one-time wife Pamela Anderson. And Hauser stars in the upcoming comedy "Queenpins" with Kristen Bell in the lead as a housewife behind the largest coupon scam in US history.
