What movie did Sophia Loren star opposite John Wayne?

Legend of the Lost is a 1957 Italian-American adventure film produced and directed by Henry Hathaway, shot in Technirama by Jack Cardiff, and starring John Wayne, Sophia Loren, and Rossano Brazzi. The location shooting for the film took place near Tripoli, Libya.

American ne'er-do-well Joe January is hired to take Paul Bonnard on an expedition into the desert in search of treasure.

Wayne and Hathaway worked together six times, beginning with The Shepherd of the Hills (1941) and ending with Wayne's Oscar-winning role in True Grit (1969). Co-author Robert Presnell, nearing the end of his career at this time, was one of Hollywood's most successful screenwriters. None of this talent managed to keep Legend of the Lost from being harshly reviewed by critics.

This film was Wayne's only collaboration on film with international cinema stars Sophia Loren and Rossano Brazzi.

The film was photographed by noted British cinematographer Jack Cardiff in Technicolor and Technirama (the wide screen process developed by the Technicolor Corporation).

Technirama is a screen process that has been used by some film production houses as an alternative to CinemaScope. It was first used in 1957 but fell into disuse in the mid-1960s. The process was invented by Technicolor and is an anamorphic process with a screen ratio the same as revised CinemaScope (2.35:1) (which became the standard), but it's actually 2.25:1 on the negative.
