Never saw Gurney as a big muscly dude. And a fair bit older looking than Momoa.
I hated the Lynch movie for the mess they made of the "magic". The SFTV series was good and had the benefit of being able to take its time. I have never seen how Dune can be a 2-3 hour movie. It's too complex.
I always saw Gurney as a stocky solid batter the walls down chap. Whereas i saw Idaho as a sleeker faster but very strong character.
It was said by Idaho that Hallek could beat him in a knife fight 6 times out of 10.
I think they both were at the top of their warrior nature, swordmaster and warmaster.
Shield fighting with knives.
It should prove very interesting, and I hope they imagine things somewhat better than superspeed camera for 'the weirding way'
-edit I like the look of all the case bar Bardem who i don't rate at all, but perhaps in this case he can make a good Stilgar. I actually quite liked the Stilgar from the miniseries, and hope Bardem channel that role to stop himself being utter *****.
