Old Ironsides
The Famous Players-Lasky released this maritime movie on December 6, 1926. Many scenes were filmed on and around California's Santa Catalina Island. The large numbers of cast and crew proved quite a challenge.
"Filmed at Catalina and the players and technicians were housed in tents. There were about 2,600 to provide for and food was served in cafeteria style in four large dining rooms seating about 500 persons. Food was brought from Los Angeles in two barges every morning." – Exhibitors Herald, May 21, 1927
"Four barge-loads of tent equipment were taken from Avalon to the Isthmus last week. It is stated that in one scene, more than 1,500 persons will be required. The pier at the Isthmus has been changed so that it typifies a waterfront scene from the historical records of Salem, Mass. Fifteen old-type sailing vessels are now anchored in the vicinity of Bird Island and Ship Rock." – Catalina Islander (Avalon, California), March 31, 1926
