Before hitting the big screen as the baddie in "Ant-Man" later this week, Corey Stoll stopped by TODAY for some small-screen fun that left viewers seeing double Wednesday morning.

Willie Geist warned Stoll that "we have a doppelganger on our staff," and then introduced the actor to stage manager Yosef Herzog for a side-by-side comparison.

"Separated at birth?" asked Natalie Morales. Guest host Ellie Kemper noted that "there's something in the eyes."

But the one person who didn't seem to see it was Herzog himself: "I think I just look like another bald dude."

Stoll countered that by sidling up to yet "another bald dude," Al Roker.

"Much better resemblance," Herzog insisted.

If Herzog looks familiar to TODAY viewers, rest assured it's not only due to his resemblance to Stoll. Kathie Lee Gifford and Hoda Kotb have turned the cameras on him more than once in the fourth hour of the show.

See more from Herzog in the clips, and catch a whole lot more of Stoll in "Ant-Man," which opens in theaters nationwide Friday.
