Still Point Turning Heather Mitchell is one of our greatest actors and the performance she gives here, as the controversial trans woman Catherine McGregor, is extraordinarily rich and multi-layered. She gives a moving portrayal of McGregor and her long and complicated path towards transition. The play’s strength is its revelations of her personal struggle. She acknowledges, in the parts of the script that are clearly based on Priscilla Jackman’s interviews, that in her early career when she was a man she benefited from the advantages that afforded, and also that now, as a trans woman, she has come to understand the invisibility that older women experience.
