Big-Hearted Bosko is a 1932 Warner Bros. Looney Tunes cartoon, featuring Bosko, the original star of the series. It was released on March 5, 1932, although one source offers for it (and other contemporary Bosko shorts) only an ambiguous release date of 1931–1932. It was, like most Looney Tunes of its time, directed by Hugh Harman; its musical direction was by Frank Marsales.
