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).
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.
