Irish actor Cillian Murphy may have enjoyed some fairly big roles earlier in his career, but it's arguably his turn as Tommy Shelby in BBC hit Peaky Blinders that's made people stand up and pay attention.
Playing the head of a Birmingham crime gang, he was suddenly seen sporting dapper period suits and a textured crop hairstyle.
And it seems that some fans got so attached to his rugged and boyish Peaky image, that they forgot about the actor behind it - who, by comparison to his on-screen character, they've branded 'ugly'.
An older image of Murphy on the red carpet began circulating on Twitter, after one person compared it to supposedly better photo, with the caption: "This actual just proves how different perspective n a hair cut can make u look."

The original tweet, which has since been deleted, received a backlash from other fans condemning the post.
One person, Jenny Molloy, said on Twitter: "The picture going around of Cillian Murphy looking different in two photos is so shameful!
"Girls give out about lads mocking them for pics with vs without makeup, but when we shame lads for looking different in pics it's funny?"
In a follow-up tweet, Jen also likened the uproar to the 'Take her swimming on the first date' memes, which involve posting photos of girls with and without makeup with the controversial caption.
Speaking to LADbible, Jen said: "I think it's shameful because a lot of girls would call guys out for doing the exact same thing - men would be called 'disgusting' or 'pigs'.
"For example, when the 'take her swimming on the first date' pictures came out, everyone went mad, saying it was horrible to shut women down like that, it's their natural appearance and they are beautiful as they are.
"But when we make fun of men for their appearance - for example, the Cillian Murphy photos - it's supposed to be funny? No, it's not funny at all - it's just mean.
"It's a two way street; it's horrible to mock both men AND women's appearances.
"If the situation was flipped, there would be outrage. I would be outraged if the original 'call out' was a picture of a female celebrity, just as I am equally outraged at the mocking of Cillian Murphy."
But others stand by their views on the post, however.
One Twitter user, who wishes to remain anonymous, simply said that they fancied Tommy Shelby, but not Cillian Murphy.
She told LADbible that comparing between an actor and their on-screen character is 'inevitable' - also adding: "You get the know the onscreen character, but you will never really know the reality of the real actor," suggesting the comparison might not always be as superficial as people might think.
So is calling someone out on looking different - either in and out of character, or with or without makeup - cruel, or just an inevitable comparison?
Well, either way, it turns out Murphy's not even a fan of the 1920s look after all - recently telling ShortList: "People like the undercut thing; people go to the barber and ask for a 'peaky cut'.
"It's crazy that people like it, it's not grown on me in four years now. I normally keep my hair long."
He also explained that the haircut has a bit of a grim past, adding: "But do the people in turtlenecks in Hackney with this haircut realise it was styled this way to prevent lice? Tell 'em they have got the lice cut, see what they say then."
