screen version of this film was photographed using Zeiss  anamorphic lenses. The system was to be called WarnerScope, but it  was essentially a straight copy of Foxs CinemaScope process.  However, Warner Bros. realized that the Zeiss lenses were of  inferior quality to the Bausch & Lomb lenses Fox used for  CinemaScope. Ultimately they decided to drop the WarnerScope name,  and instead licensed CinemaScope from Fox so they could use the  superior Bausch & Lomb designed lenses. These were first used by  Warner for the film A Star Is Born (1954).
