If they found the missing footage

A STAR IS BORN'54 was cut by Warner Bros. because they thought it too long for release. Chief omissions was a long piece of Judy Garland's character- promised and then accidentally abandoned by actor James Mason about getting a chance in pictures- trying to survive in Hollywood before Mason finds her again. When the film was restored in the mid-1980s, most of the footage was lost so they had to replace it with stills. Another cut piece was a musical number "Lose That Long Face" where Judy's character is filming the song with blissful enthusiasm while hiding her inner turmoil about Mason's self-destruction (the first and second part of this number was to surround a 'take a break' scene where Judy has a temporary emotional breakdown).

LAWRENCE OF ARABIA suffered many cuts, until the late 1980s, when director David Lean decided to restore it. Some of the negative was damaged so that the soundtrack needed redubbing, so actors Peter O'Toole, Anthony Quinn, etc. were brought back for the task (redubs for deceased actors had to be voiced by familiar-voiced, like Charles Gray, who dubbed a lot of voice-damaged Jack Hawkins' later work) with technology altering their voices to resemble their 1962 selves.

SPARTACUS received many cuts of violence and content. Chief was a 'Seduction' scene where Laurence Olivier's character is taking a bath served by slave Tony Curtis. He questions him about his liking snails or oysters- a double-entendre of male and female sex organs, which emphasizes the master's controlling sexual interest over the slave. When SPARTACUS was restored in the early 1990s, the soundtrack for this scene needed to be redubbed. Tony Curtis gave his voice, but Anthony Hopkins had to dub the late Olivier's lines.
