In Danny and the Deep Blue Sea, the two characters delve into a bitter argument at a bar. Roberta is a single mother of a teenage son who spends her evenings partying, hoping to boost her self-esteem.

Terence Rattigan’s The Deep Blue Sea is a work of genius. Inside its well-made frame, it holds such intense feeling. It’s like a pearl filled with lava, its shiny surface containing a seething heart.
