It seems like a small but talented group of actors that come from Ireland. Much like Australia, everyone of them that gets semi-famous has done it through excellence. The most well known Irish actors such are Colin Farrell and Liam Neeson. Robert is going to be one of the greats I think. Thanks Ireland! Good work lol.
Irish has got to be the best accent out there, you miss so much charm when adapting to the American version.
He looks like Jim Caviziel and Emilia Clarke's love child. As for Irish accents, that's a subjective opinion and that all depends on what part of which particular county if you ask many native Irish.
For my ears I like the cosmopolitan Dublin, rural Cork and rural Galway accents. Northern Irish accents look like they sound, Dorkish. The urban, working class Dublin accent can be a bit brutal and I think that's the one Hollywood lifted and manipulated into today's goofy Leprechaun accent.
