John Krasinski is Jack Ryan now -- and he's not here for your Harrison Ford comparisons.

Krasinski was on "The Late Show with Stephen Colbert" last night, trying to promote his new Amazon series. He worked hard to prove to Colbert that he's an "action guy" now -- and not just a nice guy who does comedy, like Jim from "The Office."

And yet -- even in the end, after defeating his nemesis in true action hero fashion -- Krasinski looked in the camera to gloat. As Colbert noted, while falling action villain style from the roof of a building: "That's soooo Jiiiiiiimmmm!"

"The Office" alum was "forced" to do 10 push-ups to prove his action chops. (The audience appreciated that.) And he had a classic stunt fight bit with Colbert. (Shout-out to the photo on the wall of Krasinski's wife and "A Quiet Place" co-star Emily Blunt.)

No action film is complete without an elevator fight, and this one had a cameo from Krasinski's "The Office" co-star Ellie Kemper.

Watch the whole thing; the action bit starts around the 3:05 mark:

Stephen Colbert does have a nice villain beard now. It works.

"Jack Ryan" is now streaming on Amazon.
