El crimen de la semana

The second of Universal-International's 3-D films directed by Jack Arnold (the first was Llegaron de otro mundo (1953)), this movie was tested in both 2-D and 3-D. Audiences did not prefer the 3-D version and (as a result of sub-standard projection of the stereoscopic 3-D process and the resulting prejudice against 3-D) many preferred the 2-D, flat version of the film. The 3-D version was rarely, if ever shown. There is no evidence that the 3-D version ever opened commercially in Los Angeles and may not even have been shown in New York or other major cities. A 3-D print does exist today, proving (in addition to the studio records) that the film was completed in that format. It premiered in Hollywood 50 years after its production, on 17 September 2003 at 3D Film Expo at the Egyptian Theatre with Kathleen Hughes (Miss 3D) in attendance.

When Don drives with Henry to the studio and "takes the wrong road", the exterior shot at that moment shows him with what appears to be a female passenger instead of a character wearing a hat, as what Henry is wearing.
