Trivia, insights & behind the scenes
RKO Pictures' Spanish-language unit briefly flourished in Mexico during Hollywood's Golden Age, producing this rare surviving noir before the studio pulled out in 1954.
Rivero explicitly modeled Yolanda's compartment scenes on Hitchcock's The Lady Vanishes, but replaced British paranoia with Mexican class anxiety.
