Nerd Cookies on Hayt the ghola

I like Jason Momoa, but does he have the acting chops to carry "Dune Messiah"? Momoa played Duncan Idaho in "Dune, Part I," but in "Dune Messiah," he will have to play Hayt, the ghola (reconstituted form) of Duncan, a cloned being who retains his original's memories but who has been trained/programmed with new and different knowledge atop the old knowledge and memories. Hayt's role in the story is complex: he's given as a gift to the emperor Paul Atreides (read my review of the novel), but he makes no bones about having been sent to eventually kill Paul. At the same time, Hayt, despite his metallic eyes and spooky demeanor, finds himself falling in love with Paul's gifted sister Alia. Can Momoa handle all of this? My one fear is that he won't have the emotional range, and he'll spend the movie with a generic frown/scowl on his face to indicate how troubled he is on the inside. Please, God, no. Momoa could easily ruin the movie if he doesn't step up. On the bright side, he played Duncan well, so he might be okay. I'd like him to be more than okay, though. I want him doing his Oscar-contending best. Hayt is arguably the emotional center of the story because of what he means to Paul (as an echo of Duncan), and what he comes to mean to Alia.
