After premiering at Sundance, the documentary It's Me, Hilary: The Man Who Drew Eloise will air on HBO on March 23. The film was produced by Lena Dunham and Jenni Konner, who also produce Girls together, though the trailer makes it look less like a traditional documentary about the life of illustrator Hilary Knight, the man responsible for drawing the famed character Eloise, and more a story of how Dunham came to know Knight. (The two met after Knight found out Dunham has a tattoo on her back of Eloise.) Looks short but sweet.
