What Maisy Knew stars Julianne Moore and Alexander Sarsgaard and tells the story of a divorcing couple and how that impacts a child’s life. One of the best in the business it’s hard to believe Julianne Moore does not yet have an Oscar but I guess she was never the prom queen in any given year. Their loss. What Maisy Knew is by the filmmaking duo who made The Deep End with Tilda Swinton (a great film if you have not yet seen it). Scott McGehee and David Siegel, adapted by Carroll Cartwright and Nancy Doyne.
