I agree, Karamo Brown from Queer Eye is stunningly beautiful, although I don't actually fancy him. Gorgeous smile and eyes.
James Norton is very handsome in an old-fashioned, well-scrubbed way, especially in Grantchester.
I don't fancy any of the Musketeers individually but I do think they are beautiful together in a job-lot sort of way.
Cillian Murphy is one of the creepiest looking humans i have ever seen like a mannequin who has come to life! This is exactly how I feel about him. My DP has a bit of a man crush on him, which I find 
Women: Eva Green I find utterly stunning, in a 'want to be her' way. And Eleanor Tomlinson in Poldark is very beautiful. Was good to see her in the Agatha Christie thing in 2017 (I think? or the year before?) playing a very different type – gorgeous in a soignée way and rather glacial.
Gillian Anderson is breathtakingly beautiful in The Fall, although it's hard to divorce her looks per se from the hair, make-up, clobber, poise, character, voice...
Then again I guess it's all about the (pardon the expression) package really, isn't it?
