Andrew Scott and Cilian Murphy have two nice short sobbing scenes in this. Too bad we don't get to see much crying or at least not the whole thing about it

   Andrew Scott starts sobbing at 33:00 on being disappointed with himself for cheating on his wife ( i think), there's some nice progression up to the point he covers his face and cracks up, when he says ''i need you'' it seems a bit dramatic to the point of being fake but maybe that's just my subjective impression.
Cilian Murphy gets a bit teary at 50:15 and at 1:00 ( when he's being rejected). Actually there aren t obvious tears shown in the second scene but he seems to sniff a bit at some point. At 1 :28 there's a scene with him in a hospital waiting room  ( not sure) after he got into a fight with the Yvonne's husband, he starts sobbing without covering his face. Too bad the scene cuts when finally we can see some tears forming in the corners of his eyes.
He also looks as if he's going to cry at the end of the movie.
