Madeline’s Madeline, the feverish, explosively creative third feature from American filmmaker Josephine Decker (Butter on the Latch) is anchored by a star-making performance from newcomer Helena Howard as Madeline, a talented but mentally ill New York teenager. Exploring ideas of race and identity, cultural appropriation and exploitation as well as the creative process, it’s a heady, fearless, incredibly invigorating work.
