Jimmy Fallon has met his match in kung fu.
Felicity Jones, star of the upcoming Rogue One: A Star Wars Story, demonstrated a few of the moves she learned in order to "make Jyn a badass" in the stand-alone film.
He apparently wasn't expecting her level of skill, though, because she immediately terrified Fallon. "Are you ready?"
"No, already I'm nervous," Fallon said, trying to urge her to go in slow motion so he wouldn't get hurt. "I'm afraid of you!"
He could barely draw his plastic toy gun before she took him out in the fight, and then bowed to the cheering Tonight Show audience.
Jones taught the Tonight Show host one of the fighting sequences from the film, which stars Jones as Jyn, who leads a group of Rebels to steal the plans for the Death Star.
Rogue One hits theaters Dec. 16.
