I just watched the fillers between the end of "Gold Diggers of 1933" and "42nd Street" and one of them was a short with Van Johnson talking about his film roles early in his career. At the end, the female voice-over announced his participation in "Thirty Seconds Over Tokyo" as playing the role of Col. James Doolittle! He doesn't! He plays pilot Capt. Ted Lawson, and Doolittle's role is well played by Spencer Tracy!
Shouldn't there be about fifty people there who should have caught that before it ever got recorded?
