'Harry Potter' cast to reunite for 20th-anniversary TV special

Twenty years after the release of the first "Harry Potter" film, movie studio Warner Bros has announced that a 20th anniversary TV special will be released on HBO on January 1, 2022. In "Return to Hogwarts," cast members, including stars Daniel Radcliffe, Emma Watson and Rupert Grint, will reunite to discuss how it all started. Author J.K. Rowling's name was not included in the announcement.

Boy wizard Harry Potter has been with us ever since author J.K. Rowling released the first book in her seven-part series in 1997. The first film adaptation was released in November 2001, with the final movie hitting cinemas a decade later. The film franchise took in some $7.8 billion (€6.9 million) at the global box office, and millions more in merchandising.

Author J.K. Rowling's "Harry Potter" spin-offs are all box office hits, but she's also been making headlines for her controversial opinions on transgender issues. Stars of her films, including Eddie Redmayne (l.), have distanced themselves from her views. They are shown here at the premiere of "Fantastic Beasts And Where To Find Them" in 2016. A sequel is set to be released in April 2022.

The Wizarding World of Harry Potter theme park opened in Florida in 2010. More parks have since opened: at Universal Studios Japan, Hollywood and Beijing. They recreate the village of Hogsmeade and Hogwarts castle. Attractions include "a one-hour exploration experience on an enchanted bench." Technically, that's true — the ride queue takes about an hour. The actual journey lasts only four minutes.

In 2014, the Diagon Alley attraction opened at the other end of the Florida theme park, with the Hogwarts Express train ready to take visitors back and forth. Alongside the Gringotts Wizarding Bank (complete with dragon on the roof), this shopping paradise for wizards and witches offers everything imaginable. Broomsticks can be purchased for a mere $250 (€220).

The top seller are the Bertie Bott's Every Flavour Beans, produced by Jelly Belly, specialists in jelly beans with amazing flavors. A delicious treat? Not necessarily — ever since the first book, it's been clear these beans can also taste pretty disgusting. Some flavors: earthworm, rotten egg, soap, grass — even vomit. But with any luck, you might find something like melon, cotton candy or cherry.

The London train station hides a "secret" access portal to the magical platform 9 3/4, where the Hogwarts Express waits to whisk students away to school. Those who want to make it through need to concentrate and aim their luggage cart directly into the brick wall. It's become a must-see site for Harry Potter fans — though Muggles, or non-magic folk, won't get very far.

This bridge wasn't recreated at the Universal theme park — it's real. It, too, has become a stop on the Harry Potter sightseeing tour, though somewhat off the beaten track in the Scottish Highlands. The Glenfinnan Viaduct was built in the late 19th century and is part of the West Highland Line. The train in the picture, however, is not the Hogwarts Express but The Jacobite, a tourist steam train.

Quidditch, a full-contact sport, actually takes place in midair. Players fly about on brooms trying to throw the Quaffle through one of their opponents' three circular gates, while avoiding treacherous Bludgers. The player who manages to catch the elusive Golden Snitch wins the game. Muggles play a version of the game on the ground, as seen here in Bonn. Without magic, of course.

While the film stars are now adults, the 2016 two-part play "Harry Potter and the Cursed Child" also looks into what happened to Harry Potter, two decades after the adventures in the books. He has become Head of the Department of Magical Law Enforcement at the Ministry of Magic and his son, Albus Severus Potter, is about to go to Hogwarts. The play is staged in different cities, including Hamburg.

The Pottermore website is the "digital heart of the magical world," home to everything fans could ever want: a space to interact, with quizzes, puzzles and — of course — an online shop. The 20th anniversary of the first Harry Potter film will not go unnoticed: "Get ready for weekly celebrations — including online events, special activities and more," says the site.
