"2001: A Space Odyssey" (1968) stargate sequence

Stanley Kubrick's masterwork 2001: A Space Odyssey (1968) combined both realistic scenes of space exploration with the the metaphysical. No sequence is more famous than the stargate approach, which was credited to Douglas Trumbull. However the slit-scan process was invented by John Whitney Sr. ten years earlier, used first in the title sequence for Vertigo (1958, dir. Alfred Hitchcock). Whitney had sent test footage to Kubrick, who apparently preferred not paying an outside contractor.
