If this is anything go by, it looks like Felicity Jones' Jyn Erso is going to have fighting skills that would put even Daisy Ridley's Rey to shame. 

The Rogue One: A Star Wars Story star popped into Jimmy Fallon to discuss the new movie and the host was insistent that Jones display some of the fighting skills that she acquired in preparing for the shoot. 

The pair armed themselves with some toy replicas of weapons used in the movie and after a "slow motion" dress rehearsal, the pair went at it for real and if the whole late night host thing doesn't work out, Fallon certainly has a future in playing incompetent Storm Troopers. 

Rogue One is out on December 15th.
