Every year for one weekend, San Diego is flooded with celebrities promoting their superhero films and fantasy shows at San Diego Comic-Con.
This year, fans got a sneak peek at footage from movies and shows including Justice League, Thor: Ragnarok and Game of Thrones.
We learned that a mysterious character, perhaps Green Lantern or a resurrected Superman, will help the rest of the heroes in Justice League, that Loki and Thor will team up in Ragnarok and that two major characters will probably meet this season on Thrones.
But fans don't just visit Comic-Con for the new clues about their favorite characters.
The convention is also a great spot for celebrity sightings. And at night, those celebrities mingle at parties, including Entertainment Weekly's annual Comic-Con bash.
