The studio production sheet lists David Lang as one of the film's writers, although his name does not appear onscreen nor in any news item or review. The CBCS gives sole screenplay credit to John McGreevey, but his name does not appear anywhere else and his contribution to the final film has not been determined.
According to a 10 May 1957 HR news item, the Mexican group "Trio Los Flamingos" was to be in the cast but their appearance in the released film has not been verified.
