I feel sorry for Madge Bellamy in John Ford's The Iron Horse (1924). Despite all her feminine wiles, her perky coquettishness and her distracting petulance, she has to work to keep my eyes on her. They keep roaming over to appreciate her leading man George O'Brien in his first feature role as Davy Brandon. Brief bios on O'Brien abound including IMDb and Wikipedia; and; most recently, BearManor Media has published David W. Menafee's George O'Brien: A Man's Man In Hollywood (2010. I'll let those resources speak for themselves and offer up a gallery.
