Rafe Spall

Appeared in all three of Edgar Wright's "Cornetto Trilogy" movies: in Shaun of the Dead he played Shaun's young workmate; in Arma fatal (2007) he is one of Pegg's fellow cops (albeit a goading one, like he was in Shaun); and in Bienvenidos al fin del mundo (2013) he has more of a cameo.

Then when they [children] get bigger, you're thinking: 'Now I have to create a good person - a proper human being.' And, seriously, the responsibility of that isn't lost on me.
