The 2006 Documentary from Bryan Singer and Kevin Burns

From Wikipedia:

A 2006 documentary film from executive producers Bryan Singer and Kevin Burns which details the history of the Superman franchise, from comic book, to television, to the big screen. The story of Superman is told through archival footage, as well as interviews with many of the actors, directors, and producers involved with the Superman media over the years. The closing credits feature outtakes from the Christopher Reeve Superman films, including an outtake of Marlon Brando improvising during the recitation of a poem in a scene deleted from the original version of Superman II. The documentary was released on DVD on June 20, 2006, shortly before the theatrical release of Superman Returns.
