In the later stages of his career, Lionel Barrymore was often cast as an irascible millionaire plagued with irresponsible children. In 1917's His Father's Son, it was Barrymore who played the ne'er-do-well offspring, while Charles Eldridge portrayed his father. Thrown out of his dad's house without a penny to his name, playboy J. Dabney Barron (Barrymore) is told not to return until he has proven that he can keep a job for an entire month. After several false starts, our hero is hired to keep flighty heiress Betty Arden (Irene Howley) out of trouble. He not only succeeds but manages to get his hands on a valuable jewel that has long been coveted by his father. His Father's Son was another joint effort by those busy wordsmiths Channing Pollock and Rennold Wolf. ~ Hal Erickson, Rovi
