Francis X Bushman Jr

As his name makes clear, Francis Everly Bushman (1903-78) was the son of the screen’s original Messala in Ben-Hur (1925), who himself made an uncredited appearance in Thoroughbreds Don’t Cry. 

Bushman Jr had a less prestigious career, though he did feature in They Learned About Women as the practical joker Haskins. Some years later he turned up uncredited in Let Freedom Ring.
