AllMovie

Filmed on location in Mexico (one of several Hollywood-financed films of the 1950s to take advantage of the lower production and labor costs south of the border), One Big Affair stars Evelyn Keyes as Jean Harper, a scatter-brained American schoolteacher and Dennis O'Keefe as Jimmy Donovan, a stateside lawyer. When Jean is separated from her tour group, it is assumed that she's been kidnapped. In fact, she has fallen in love with fellow tourist Donovan, and has joined him in his journey to Acapulco. The local constabulary refuse to believe that Donovan isn't a kidnapper, and a zany chase across Mexico ensues. One Big Affair was produced by the estimable Benedict Bogaeus, on the verge of his lucrative association with RKO Radio, and director Allan Dwan.
