Ann Pennington is a legend. She was a Ziegfeld girl and one of the biggest stars of the 10-20's. Unfortunately she made only a handful movies. I guess it was a little too late in her career to become a movie star. In this clip she's 36 and younger girls with dancing skills were waiting in the wings.
Broadway star Allen Kearns is not famous for his movies, he made only three. Sadly, today both of them are quite forgotten.
