"1776 is a 1972 American musical film directed by Peter H. Hunt. The screenplay by Peter Stone was adapted from his libretto for the 1969 stage musical of the same name. Portions of the dialogue and some of the song lyrics were taken directly from the letters and memoirs of the actual participants of the Second Continental Congress. The song score was composed by Sherman Edwards."
