The use of several uncredited, but recognizable players in dual roles results in some odd situations: Sidney Bracey is first seen at the Burbank Airport starting point, then later he's in the crowd at Cleveland at the finish line.
This film did well both critically and financially for Warner Brothers' B-Picture unit. In a review, "Film Daily" wrote "Mark Hellinger Associate Producer, uncredited can take full credit for an excellently mounted, well cast and carried out production." Most of the other reviews marveled that so much had been done with so little.
