Chris Hemsworth returns as the Avengers’ resident thunder god in ‘Thor: Ragnarok.’

Geek nirvana is upon us again.

Nerd-friendly blockbusters-to-be like Justice League and Blade Runner 2049 and hugely popular TV series The Walking Dead, Game of Thrones and Westworld will be among the many featured at Comic-Con, which runs Thursday through Sunday and will bring more than 125,000 fans to San Diego.

Here are the five questions we most want to see answered:

Q. Will Deadpool crash the Kingsman panel?

A: Thursday’s 20th Century Fox movie panel is slated to be all about the spy sequel Kingsman: The Golden Circle, with Taron Egerton as a young James Bond type. But with a Deadpool follow-up out next June, could Ryan Reynolds and/or his merc with a mouth show up to steal some thunder? If so, “he’ll get a Kingsman kick up the backseat,” director Matthew Vaughan says with a laugh. 

Q. Is 2017 the year Netflix takes over Comic-Con?

A: The streaming service is following up a slew of Emmy nominations with a large presence. A movie-centric Thursday panel will host Will Smith from the fantasy action thriller Bright, as well as the cast of the Japanese manga adaptation Death Note. Netflix superhero stars Charlie Cox, Krysten Ritter, Mike Colter and Finn Jones will take the stage Friday for supergroup show The Defenders. And everyone’s favorite ’80s kids get a showcase on Saturday for the upcoming second season of pop-culture breakout Stranger Things.
