Woody Harrelson has signed on to star in ‘Fruit Loops,’ the latest offering from ‘Hidden Figures’ and ‘St. Vincent’ writer-director Theodore Melfi. Per THR, the dramedy centres on a group of mental patients who band together when their hospital suddenly sells. Harrelson would play Colonel Leonard F. Cubby, who suffers from severe PTSD from his tours in Vietnam. Peter Chernin and Jenno Topping, who previously worked with Melfi on ‘St. Vincent’ and ‘Hidden Figures,’ are on board to produce.
