Myrna Loy was actually a fully trained professional dancer, having studied with Ted Shawn (husband of modern dancer Ruth St. Denis and co-leader with her of the Denishawn company), but "The Truth About Youth" and Warners' all-star musical "The Show of Shows" were among the few movies in which she actually got to dance.
In the late 1920's and early 1930's, several films, instead of crediting their directors as such, listed the director's name as "A (blank) Production" on the same card as the main title credit.
