I've been imagining Gwyn looking similar to Varro for the Spartacus TV series. I started rewatching Spartacus out of boredom, and when Varro appeared on screen I thought he could be a good fit for Gwyn - tall, ripped warrior's body, loads of blond curls, good-looking but at the same time kind of cute. It was mainly the hair. Quote my housemate: "I want to boing his curls".
While Gwyn’s curls are way way floofier (and also his shoulders are broader because he’s a swordmaster and not like…beefing out in a gymnasium - the physique of professional sword fighters who wear medieval style plate armour is actually a fair bit different to what we’d associate with being ‘ripped’ today - and being ‘ripped’ today is often not at all functional for warriors of the past - but that’s all we have to cast swordfighters in period TV and movies so….the inaccuracies remain), I can definitely see why folks like yourself would see Gwyn/Varro as being compatible!
(That makes way more sense to me than the Augus/Hiddleston comparison anyway - though that’s just me being a stupidly fussy author and not like, anything to do with reality where people could facecast Augus with Sportacus if they wanted to and I can’t stop them - all I can do is put the descriptions in the text, which people are welcome to ignore as much as they like, that’s the gift the reader gives :D lol - (I know that, because I frequently ignore author descriptions, especially if I accidentally got an image in my head before I got a really thorough description; this is also the same mechanism of how a billion people thought Rue was white in Hunger Games incidentally, despite actual descriptors - people see what they like and it has very little to do with what I say)).
(But the floof of Gwyn’s curls are epic. Like, if you pressed down on the top of the curls you’d at least go through about two good inches of just hair before you reached his scalp. (Incidentally Gwyn with wet hair is hilarious. His hair is actually fairly long, but because it boings up into huge ridiculous curls, you don’t realise that until he’s sporting the wet dog look and Augus is trying not to laugh at him). But otherwise like I’m looking at pictures of Varro right now like y’know, he would’ve been good to reference about a billion years ago when artists started asking: ‘what actor does Gwyn look like?’ Him along with the dude who plays Dyson from Lost Girl (sans facial hair) and I think there was like an ice skater dude as well.)
