No Best Picture winner has been lost, though a few such as All Quiet on the Western Front and Lawrence of Arabia exist only in a form altered from their original, award-winning release form. This has usually been due to editing for reissue (and subsequently partly restored by archivists). Other winners and nominees, such as Tom Jones (prior to its 2018 reissues by The Criterion Collection and the British Film Institute) and Star Wars, are widely available only in subsequently altered versions. The Broadway Melody originally had some sequences photographed in two-color Technicolor. This footage survives only in black and white.[34]
