This is a very intense scene between Hugh Laurie and Imelda Staunton in "Peter's Friends". They play a couple whose marriage is collapsing after the sudden death of one of their infant twins. Here, he confronts her about her obsessive behavior towards their surviving son. The crying (hysterical) is mostly on her part, but Laurie is teary too (it's mostly in his voice). I think this was the first time he had done dramatic acting.  Beautifully played by both of them in one uncut take.
