This two-hour tour is one of the best studio tours in Hollywood. The groups are small (12 people at a time), and you are taken past working sets. Visitors ride through the backlots on a small tram-like vehicle. You are allowed to get off and peek at the sets. You are also taken to the 'front lot' where current TV shows such as 'Gilmore Girls' and 'Joey' are filmed. If you are lucky, you will see some actors rehearsing their lines. At the end, visitors get to see the Warner Bros. Museum, which houses memorabilia from the studio's 70 year history.
