Uncanny Resemblance: Barry Keogh and Alana Haim look alike

Watching "Crime 101" and there was a close up of Barry Keoghan's eyes while he is wearing a balaclava. (Scene at 1:39:10) I immediately thought of Alana Haim in "Licorice Pizza". Given their resemblance, I think they could play brother and sister in a film. 

Put some gray in his hair and Joel Edgerton could play their dad.
