Sea Devils' leading lady, Molly O'Day, was the younger sister of popular silent star Sally O'Neil. Only a schoolgirl when Hal Roach selected her to join his Our Gang series, she would also appear with Laurel and Hardy in 45 Minutes from Hollywood (1926). Like her sister, she was chosen as one of the WAMPAS Baby Stars in 1928. Leading man Edmund Burns began his career as an extra in D.W. Griffith's The Birth of a Nation (1915), and starred in features such as East is West (1922), The Humming Bird (1924) and The Princess from Hoboken (1927), the latter alongside a young Boris Karloff. Walter Long also appeared in The Birth of a Nation, notoriously as one of the actors in blackface. However, he is better remembered for playing the villain in several Laurel & Hardy films, including Going Bye-Bye! and The Live Ghost (both 1934). Hilliard Karr, one of the "Three Fatties" from the Ton of Fun series, has an uncredited cameo as a bartender.
