I'm actually five eight, though. I'm not that short. I mean, I'm short, but Archie [Madekwe] as well is quite tall.

Hi Rob,
Barry Kehogan, Jeremy Allen White, Tom Holland, Cillian Murphy, James McAvoy, Kit Harington. Short guys for Hollywood standards, but they all manage to get leading roles in movies and TV shows. Is it just a case or maybe height is less of an issue nowadays? I mean, Alan Ladd used to stand on a box in order to be believable as a male leading charachter...

Good spot, it's a better claim than what he was given by agency.

How tall would you guess Cosmo Jarvis who stars with him in Calm with Horses ?

Editor Rob
Looking at a clip of them, he does seem at least 3 inches taller.

In the banshees of Inisherian he looks 2.5-3 inches shorter than 177cmish colin Farrell. 5'7 seems plausible.

I think the reason he claims 5’9 is because his legs look super long for someone whose only 5’7, and his arms look a bit short too

You can tell as well when he sits down too, or isn’t hiding his proportions in a suit

My guess is he’s only 5’6.5.

God so many people think 5'9" is short lol, it is as average as you can get. Barry is a legit 5'7"

5ft9 - my eye! More like 5ft7! He played his warped and creepy part very well in 'The Killing of a Sacred Deer' -as a softly-spoken 16-year-old, hell bent on revenge! Yuck!
I'll go with 5ft7.

Looks like a shorter version of Ezra Miller.

He is clearly no taller than 5"7.Important to note also that Cillian Murphy looked the same height in photos, so his 5"9 claim is a joke.
