Jason Momoa described this character as “Han Solo-esque,” but instead of being good at a blaster, Duncan Idaho is a master swordsman who acts as the right-hand man to Duke Leto (Oscar Isaac).
Sounds about par for the course for Jason Momoa.
Before that though, he’ll appear on the big screen much sooner as Duncan Idaho in the epic science fiction adaptation of Dune directed by Denis Villeneuve.
