The phenomenal box-office performance of "The Sound of Music" gave the major Hollywood studios more confidence to produce lengthy, large-budget musicals. Despite the resounding success of some of these films, Hollywood also produced a large number of musical flops in the late 1960s and early 1970s which appeared to seriously misjudge public taste. The commercially and/or critically unsuccessful films included "Camelot", "Finian's Rainbow", "Hello Dolly!", "Sweet Charity", "Doctor Dolittle", "Half a Sixpence", "The Happiest Millionaire", "Star!", "Darling Lili", "Goodbye, Mr. Chips", "Paint Your Wagon", "Song of Norway", "On a Clear Day You Can See Forever", "Man of La Mancha", "Lost Horizon", and "Mame". Collectively and individually these failures affected the financial viability of several major studios.
