Champions Forever: World Heavyweight Champs (1989)

Champions Forever is filmmaker Dimitri Logothetis' bouquet to past boxing greats. Adopting a "then and now" approach, Logothetis alternates clips of these fighters in their prime with recently filmed interviews. The five boxers spotlighted herein are Muhammad Ali, Joe Frazier, Ken Norton, Larry Holmes, and George Foreman--whose "prime", it would later turn out, hadn't quite passed yet.
