Paramount Pictures
With a history dating to the early 1920s, the Paramount lot was home to some of Hollywood's most luminous stars, including Mary Pickford, Rudolph Valentino, Mae West, Marlene Dietrich, and Bing Crosby. Director Cecil B. DeMille's base of operations for decades, Paramount offers probably the most authentic studio tour, giving you a real sense of the film industry's history. This is the only major studio from film's golden age left in Hollywood—all the others are now in Burbank, Universal City, or Culver City.
Memorable movies and TV shows with scenes shot here include Sunset Boulevard, Forrest Gump, and Titanic. Many of the Star Trek movies and TV series were shot entirely or in part here, and several seasons of I Love Lucy were shot on the portion of the lot Paramount acquired in 1967 from Lucille Ball. You can take a two-hour studio tour or a 4½-hour VIP tour, led by guides who walk and trolley you around the backlots. As well as gleaning some gossipy history, you'll spot the sets of TV and film shoots in progress. Reserve ahead for tours, which are for those ages 10 and up.
You can be part of the audience for live TV tapings (tickets are free), but you must book ahead.
