The younger brother of silent-film leading man Bobby Harron, John Harron began his own screen career in 1921, a year after his brother's accidental death. John most often played callow juveniles and lightweight romantic leads. His transition to talkies was a difficult one; except for worthwhile parts in such independent productions as White Zombie (1932), Harron was largely limited to nondescript minor roles. John Harron briefly rallied with a string of good character roles in Warner Bros.' "B" product of the late 1930s, but his comeback was cut short by his untimely death at the age of 37. ~ Hal Erickson, Rovi
