Bo Derek gives the Hollywood Navy salute

Actors aweigh! Admiral Bo Derek snaps off a brisk naval salute as she arrives at the finale of the fifth season of the show American Idol, held at the Kodak Theater in Hollywood, California. The date was May 24 of 2006, the year that Bo Derek turned 50. At this point, Bo Derek was a rear admiral in the Hollywood Navy, having joined the ROTC at age 20 while shooting her first film, Orca (1977). She rose through the ranks quickly; her famous beach-running scene in the film 10 was a insider nod to her youthful passion for the sea. Per the traditions of the Hollywood Navy, Derek wears an admiral's embroidered flowers on her shoulders rather than the classic shoulder boards; each leaf represents either a successful drug interdiction or a film completed. The lace around her sleeve indicates her active-duty status. Derek was the first woman to reach the rank of admiral in the history of the Hollywood Navy, which was founded in 1939 by actors and sailors Errol Flynn and Humphrey Bogart. Previously, Doris Day had reached the rank of Chief Warrant Officer 5 (CWO-5).
