The Prizefighter and the Lady (1933)

Steve is just a heavy duty bartender when Edwin J. Bennett, known as the Professor, starts training him for the ring. While doing road work, he is almost killed by a speeding car which crashes into a ditch. In the car is Belle Mercer and her driver. Steve takes Belle to a farmhouse and is smitten by her, but she is Willie Ryan's girl. The fight is a breeze and later, Steve again meets Belle with Willie. That night, Steve and Belle disappear and return married, much to Ryan's disappointment. Then Steve starts training in earnest and is 19 for 19 in the ring. However, he has an eye for the women and an expanding ego to match.
