A few cast members in studio records/casting call lists for this movie were not seen in the final print. These were (with their character names, if any): Bobby Caldwell (Happy as a Boy), William Demarest (Ringmaster), and William B. Davidson. Tom Dugan was also not seen in the print, but he was credited in position 11 as "Mac."
According to a review summary in the New York Times, Joe E. Brown was affectionately pawed by a lion during one take, requiring 6 stitches in his arm. The article also points out that Brown did his own "spectacular acrobatics" - no doubles were used.
