Tens of thousands of cosplayers will descend on San Diego on Thursday for the first full-fledged Comic-Con in three years, with new “Lord of the Rings” and “Game of Thrones” TV series set to be revealed at the world’s greatest pop culture gathering.

Hollywood studios such as Disney and Warner Bros. are also in town to promote their new movies and have done nothing to quell rumors of the first look at Marvel superhero sequel “Black Panther: Wakanda Forever” and a public release of a new Superman film.

Due to the spread of COVID-19, the previous two Comic-Cons had to be held online, and only a small number of people attended a scaled-down “special edition” in San Diego last November.

However, attendance this week is intended to satisfy pre-pandemic levels, with over 130,000 fans expected to wear face masks as they pack into the sweaty convention center dressed as hobbits, dragons, or princesses.

“I think it’ll look like Comic-Con from 2019,” said David Glanzer, the event’s communications and strategy chief.

“We weathered it. And now coming back, maybe we’re going to have tears of joy… it’s very emotional,” he told AFP.

The extravaganza of comic books, science fiction, and fantasy kicks off this year with Paramount’s “Dungeons and Dragons: Honor Among Thieves.”

The film, starring Chris Pine, Hugh Grant, and former “Bridgerton” heartthrob Rege-Jean Page, will be released in March, represents the first time the biggest and most popular role-playing game has been adapted for the big screen.

However, two massive fantasy series are set to conquer the week’s headlines: Amazon Prime’s “Lord of the Rings: The Rings of Power” and HBO’s “House of the Dragon.”

“The Rings of Power” is Amazon’s massively aspirational saga set in the world of J.R.R. Tolkien’s books and currently happening many years by the time of Peter Jackson’s Oscar-winning trilogy of films.

The five-season series, one of which premieres on September 2, is said to have cost Amazon well over $1 billion and is said to be an individual addiction of founder Jeff Bezos.

All of that money was spent on acquiring the privileges to the Tolkien universe and luxurious special effects, with a sizable chunk set aside for “activations,” or interactive fan experiences, at Comic-Con.

Amazon would therefore bring its cast of hobbits, elves, and dwarves to the venue’s cavernous Hall H on Friday, in which fans will enter for hours or even days to have a first deeper look at the sequence.
