Happy Birthdate, Willard Mack!
September 18 is the birthdate of Canadian actor Willard Mack, born in 1873. He was active on Broadway, writing 23 plays and performing in numerous stage productions. He only appeared in a dozen or so movies, and Aloha Oe, filmed in 1915 at a million-dollar estate in Montecito, CA, was one of these few. The movie takes place in Hawaii, but the filming never got any further west than the Gillespie estate.
This was probably fortunate because Mack was injured during the filming. "Willard Mack sustained a severe injury to his back recently while carrying Enid Markey down a slippery mountainside in the picture Aloha Oe. – Motion Picture Magazine, October 1915
