Barrington wrote horse racing columns for "Punch" magazine under the pseudonym "Lady Gay" and also wrote two volumes of reminiscences, in 1908 and 1911. He also appeared in four silent films: "San Toy" (1900); as Mr. Texel in "The Great Adventure" (1915); as Septimus Beaumont in "The Girl Who Loves a Soldier" (1916); and as Mr. Potter in "Still Waters Run Deep" (1916). In addition to his avid interest in several sports, which he describes at length in his memoirs, Barrington was a skilled artist in watercolours and pen and ink.
