Horizontes perdidos

This movie was the first one Columbia Pictures filmed after it moved onto the Warner Brothers lot in 1972, creating The Burbank Studios, to facilitate both production companies. The castle set from Camelot (1967) was recycled as Shangri-La. The medieval turrets were removed and replaced with Tibetan gables to simulate Himalayan Buddhist monasteries. Most of the castle's lower levels remained intact, and the courtyard was replaced with layered steppes and fountains. The set remained on the studio's backlot for several years before it was torn down to make way for a new office building.

The library at Shangri-La is supposed to be a repository for the world's great literature, yet a number of "Readers' Digest Condensed Books" are visible on its shelves.

"Lost Horizon" was cut by 23 minutes after its theatrical release. The deleted footage consisted of three songs: "I Come To You", "If I Could Go Back", and "Where Knowledge Ends, Faith Begins"; plus two reprises of "Living Together, Growing Together" were cut, and a fertility dance sequence was also edited out. Pioneer reinstated the three songs for a 1992 Laserdisc release whilst the remaining footage was restored for the 2011 DVD version.

Edited into Mandrake (1979)
