Fans of Jason Momoa's signature beard – look away nowWith Jason Momoa currently getting ready to reprise his role as Duncan Idaho in the upcoming third Dune film, he’s had to undergo quite a transformation to get into character – namely, shaving off his beard for the first time in six years.The last time Jason was seen bare-faced was in the first instalment in Denis Villeneuve’s Oscar-winning sci-fi saga. Because of this, he has once again had to break out the clippers to step back into the role of Duncan.In a video posted on Instagram on Wednesday evening (in collaboration with his water brand Manalalu), Jason explained that he’d been growing his beard in the six years since shooting the first Dune film.
