A little history about Building Four, on the 20th Century Fox Studios.
I occupied one of the rooms in a building that was built in 1929, used then for editing foreign version of Fox films. By the 1950's, it was the international department that was responsible for shipping completed film for the foreign market, complete with sound effects and music tracks, ready for lip-sync dubbing.
