Visitors to the newly expanded and re-opened Warner Bros. studio lot can once again immerse themselves in 100 years of television and filmmaking at the Los Angeles attraction, including climbing into Harry Potter’s cupboard under the stairs, discovering Batman’s secret cave, and hanging out with “Friends” in Monica and Rachel’s iconic New York apartment.

Closed for more than a year due to the pandemic, the Warner Bros. Studio Tour Hollywood has re-opened and featuring a fresh focus on the DC and Harry Potter universes. Now welcoming families with children ages five and older, the tour follows all city, state, and federal COVID-19 safety protocols.

The expansion — which includes a new building — took five years to develop in Burbank.

“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 in late June.

Here are some of the tour’s key features:

STORYTELLING SHOWCASE

Selfie opportunities are a-plenty at the replicated signature “WB” water tower as attendees are able to walk along an aerial view of the sprawling studio lot. The walls are lined with mementos of the studio’s film, TV animation titles, dating back to 1923. Some of the highlights in this room include photos from classic films such as “Casablanca” and “Little Caesar.”

There is a dedicated wall area of the Oscar-winning film “Million Dollar Baby” and the boxing gloves worn by Hilary Swank. J.R.’ Ewing’s boots and hat from the television series “Dallas” are also on display. Several miniature soundstages with the words “Please do not sit” are throughout the exhibit.

DC UNIVERSE

Visitors are able to step into the behind-the-scenes universe of DC superheroes and villains. One of the compelling aspects is the secret Batcave, where guests will find the authentic Batmobile from Tim Burton’s original “Batman,” the Tumbler from “The Dark Knight,” and the Batwing from “Batman v. Superman.”

Costumes worn by Superman, Batman, Wonder Woman, Aquaman, and the Flash are on display. Other standouts include Margot Robbie’s Harley Quinn and Jared Leto’s Joker costumes from “Suicide Squad.” Along with Christopher Reeve’s “Superman” costume, the exhibit has Michael Keaton’s suit from the 1989 film “Batman” and Lynda Carter’s “Wonder Woman” costume from the classic 1970s television show.

In an interactive experience, visitors can touch the glowing Lasso of Hestia from “Wonder Woman 1984.”

HARRY POTTER & FANTASTIC BEASTS

Tour participants can create a photo opportunity inside Harry Potter’s cupboard under the stairs at 4 Privet Dr. and understand the art of making potions on the re-created sets of “Harry Potter” and “Fantastic Beasts.”

Or sit underneath the Sorting Hat, which determines one’s Hogwarts house. And class is in session to learn about the unique creatures at Newt Scamander’s Shed of Magical Creatures.

“You get to experience the action, the magic and fun, and the props and costumes and the re-created sets,” said Bonnie Wright, who starred as Ginny Weasley in the Harry Potter film series, at the tour’s re-opening.

FRIENDS BOUTIQUE

Stage 48: Script to Screen is home to the “Friends” boutique that is accompanied by the expanded Central Perk Café. The area features re-created sets inspired by the show including Joey and Chandler’s apartment, Monica’s apartment, and Central Perk. Some costumes worn by the cast and other props from the show are from the 25th anniversary in 2019. Monica’s famous door frame and a “Friends” reunion-inspired spirit jersey, coffee mugs, along with souvenirs and collectibles are included.

Central Perk offers a New York deli-inspired menu that includes a special blend of Central Perk coffee, pizza wedges, corned beef melts and cold sandwiches.

“I don’t think people are going to want to leave,” said Maggie Wheeler, who played the recurring role of Janice on “Friends,” which starred Jennifer Aniston, Courtney Cox, David Schwimmer, Matt LeBlanc and Lisa Kudrow.

“It feels like the show,” Wheeler continued. “It feels like memory lane. I think people are going to be really, really excited to walk through and spend time here.”

CELEBRATE AWARDS SEASON

The tour concludes with an exhibit spotlighting costumes and props, including the jersey worn by the late Chadwick Boseman as Jackie Robinson in the film “42” and the miniature blimp from Ridley Scott’s “Blade Runner.” The trombone that Robert Preston played in “The Music Man” is also on display.

Guests will have an opportunity to hold an authentic Oscar trophy. (Be sure to grasp with both hands. It’s heavy.)
