It's all True: Based on an Unfinished Film by Orson Welles 

Only the final segment of It's All True, Orson Welles' legendary uncompleted film, survived--in the form of unedited rushes--in its entirety. That segment, called Four Men on a Raft, has been reconstructed for this documentary chronicling the adventures of Hollywood's greatest enfant terrible in the tropics. Also included is footage from the remaining segments, My Friend Bonito and Carnaval.
