Son of the late-great actor, James Cagney, James Jr. was adopted along with
sister Cathleen (nickname "Casey") by the senior Cagney and wife 'Bill'
in the early forties. James Jr. pre-deceased both his parents, dying of
a heart attack in the early eighties. His appearance in "The Gallant
Hours" as an infantryman was accompanied by a similarly brief
appearance of director Robert Montgomery's son, Bob Jr.
