Secretive Kubrick
Kubrick demanded extreme secrecy for 2001: A Space Odyssey, ordering props destroyed to prevent replicas and insisting that all outtakes be eliminated.
After premiering the movie, he even cut 19 minutes for pacing and instructed that the removed footage be destroyed.
For decades, fans believed it was gone forever - until 2010, when 17 minutes were rediscovered in a Kansas salt mine, perfectly preserved.
Visual effects legend Douglas Trumbull has since expressed hope that stills and frames from the lost scenes may appear in a future archival project.
