I. Y. Yunioshi is a fictional character conceived by Truman Capote for his 1958 novella Breakfast at Tiffany's, which George Axelrod adapted for the 1961 movie of the same name. The character in the film is significantly different from the character as presented in Capote's original novella, and the film version of Mr. Yunioshi, as portrayed by Mickey Rooney, has been the subject of extensive critical commentary and review since its theatrical release due to its use of ethnic stereotypes.
