Filming in Hollywood isn't limited to the inside of the movie studios. Much of what you see on the silver screen is shot outside, on location right on the streets of L.A., and the surrounding communities. In fact, it's hard to turn around in this town around without bumping into a site where a well-known movie or TV series was shot. Producers use virtually all of Los Angeles and Orange County as one giant movie set. Take a look at any major motion picture and you're likely to recognize the downtown L.A. skyline, the Sunset Strip, Hollywood Boulevard, Marina Del Rey, Malibu, or Rodeo Drive. But those well-known sights are only the beginning.
