Kept in mind for his roles in a huge selection of silent motion pictures from the 1910s and ’20s, Kerrigan could very well be most widely known for his portrayal of protagonist Can Banion within the 1923 traditional western feature The Protected Wagon. He started his entertainment profession like a vaudeville performer and made an appearance in his 1st silent film, a traditional western short entitled Calamity Anne’s Inheritance, in early 1913. He stirred controversy and dropped profession momentum when, in 1917, he publicly mentioned that only males who were not really “best for other things” should battle in World Battle I, which it was regrettable that artists weren’t exempt from armed service support. In 1914, he started a far more than three-decade romantic relationship with fellow acting professional and director Wayne Vincent. When stage and display story John Barrymore was struggling to play the name role within the 1924 silent film Captain Bloodstream, Kerrigan overran the part.
