This feature documentary focuses on the brilliant, but eccentric, late singer-songwriter Harry Nilsson. The Beatles once proclaimed Nilsson as "their favorite group," and he was on top of the world in the early '70s, courted by the elite of popular music and film. (He became best friends with the Beatles and Ringo was his best man.) He was riding the crest of a remarkable wave of success. Yet, in just a few short years, his glorious voice would be in tatters, his health ruined and he would be without a record contract.
