The screenplay was written for Loretta Young, George Brent, and Joel McCrea but later was given to Clark Gable, Joan Crawford, and Robert Montgomery.
Forsaking All Others (1934) was the sixth of eight films Joan Crawford made with Clark Gable. The two had been on-and-off lovers since Possessed (1931), and even though Crawford was already involved with Franchot Tone, who would become her second husband, her romantic chemistry with Gable is still evident and potent.
Forsaking All Others (1934) was based upon a 1933 play by Edward Barry Roberts and Frank Cavett. The original play opened in New York City, New York, USA on 1 March 1933 and had 110 performance. Tallulah Bankhead played Mary Clay, and the cast included Ilka Chase, Barbara O'Neil, Cora Witherspoon, Fred Keating, Anderson Lawler, Harlan Briggs, and George Lessey.
This film ran into many problems with the new Production Code Office, resulting in retakes being shot up until just two weeks from the picture's release.
