BURBANK

Batman’s secret cave, Harry Potter’s cupboard under the stairs and the apartment from “Friends” are major centerpieces to the huge Warner Bros. studio lot expansion.

Warner Bros. Studio Tour Hollywood recently reopened more than a year after doors were shuttered because of the coronavirus pandemic. Now, attendees will have a chance to explore the studio’s nearly 100 years of television and filmmaking history, highlighting the DC Universe and “Harry Potter.”

A firsthand look took place a couple of days before the tour opened in late June at the Southern California studio, which now welcomes families with children ages 5 and older.

Warner Bros. officials said the expansion — that includes a new building — took five years to develop in Burbank. Officials say the studio tour will follow all city, state, and federal COVID-19 safety protocols.

“One of the most incredible things about Warner Brothers is the incredible history of epic films that are legendary,” said “Wonder Woman” director Patty Jenkins, who helped reopen the tour.
