Irish actor J. M. Kerrigan was a stalwart of Dublin's Abbey Players, though from time to time he'd make the crossing to America to appear in such films as Little Old New York (1923) and Song O' My Heart (1930) (His film debut was 1916's Food of Love). Kerrigan settled in Hollywood permanently in 1935 when he was brought from Ireland with several other Abbey performers to appear in John Ford's The Informer. Kerrigan was given a generous amount of screen time as the barfly who befriends the suddenly wealthy Victor McLaglen, then drops his "pal" like a hot potato when the money runs out. Not all of Kerrigan's subsequent Hollywood performances were this meaty, and in fact the actor did a lot of day-player work, sometimes showing up for only one or two scenes. It was in one of these minor roles that J. M. Kerrigan shone in Gone with the Wind (1939), playing Johnny Gallegher, the seemingly jovial mill owner who whips his convict labor into "cooperation."
