Sikkim, a 1971 documentary about the tiny Himalayan kingdom, was suppressed by Indian censors because it was found to glorify monarchy. (The statelet was a sensitive subject: India went on to annex Sikkim in 1975.) A print of the film, thought to have been destroyed, turned up at the British Film Institute in 2003 and “was restored digitally frame-by-frame by the Academy of Motion Picture Arts and Sciences.”
