Griffith Observatory’s role in the movies is discussed. It has been in so many movies, it should have a star on Hollywood Boulevard. The Observatory's first film credit, The Phantom Empire, was shot even before the observatory opened to the public in May, 1935. As a film star, Griffith Observatory fulfilled a variety of predictable and often peripheral functions, but in two movies, Rebel without a Cause and La La Land, the observatory was key to the theme. Griffith Observatory's relationship with Hollywood is, however, deeper than all of these on-screen close-ups. At times, Griffith Observatory influenced Hollywood, and Hollywood technology, production standards, and storytelling priorities have all, over more than eight decades, been absorbed by Griffith Observatory.
