It is time once again for one of the biggest gatherings worldwide of people who love superheroes and other characters from comic books, films and television. San Diego Comic-Con is back for a 50th straight year. Established in 1970, the four-and-a-half day event in San Diego, California, started with the show room opening Wednesday. Thousands of fans arrived looking to buy items linked to their favorite stories and characters that they cannot get elsewhere, including clothing and art. Many moviemakers come to San Diego Comic-Con to present the films they are working on. The production company Warner Bros. held an event called ScareDiego in which it showed a small part of its frightening new film, It: Chapter Two. British fan Cheryl Dolbel told the Associated Press, “This is my favorite. I’m a huge Stephen King fan.” Stephen King wrote the book on which the films are based.
