I heard about this in a unique way last year, and it's quite a troika - Robyn Nevin in a Lally Katz-authored play directed by Simon Stone (I only found out that last looking at a poster after the show, but it made sense - the production's stagecraft has his fingerprints all over it). There was always the risk of dullness, slightness, in the premise of a story focusing primarily on one (old, irascible, Hungarian) individual and her relationship with the author-proxy character, but the play avoids that through the strong characterisation of Ana (as written and performed), the quality of the writing and the effective way it uses the stage (including the revolving floor sections) and lighting - shadows (Stone's touch apparent there) - to generate a sense of movement and mood.
