Jonsson joined Oscar-winning “Black Panther” franchise director Ryan Coogler on stage alongside Letitia Wright and Winston Duke, holding his hand to his chest and smiling broadly. “Black Panther III” is set for release Dec. 15, 2028.

“Thank you to this family that I have the honor and the blessing to join. I don’t want to say too much, because I want to let the screen do the talking,” said the 32-year-old actor, known for roles in “Industry,” “The Long Walk” and “Alien: Romulus.”

Boseman died in 2020, and ever since 2022’s “Black Panther: Wakanda Forever” revealed that T’Challa had a son, fans have been playing a guessing game of who might take over the mantle, with Damson Idris and Wright in the mix. The original 2018 “Black Panther” became the first superhero film to earn a best picture Oscar nomination and made more than $1.3 billion worldwide, while the sequel earned $850 million.

Ryan Gosling rides into the MCU

Gosling will re-team with his “Star Wars: Starfighter” director Shawn Levy on “Ghost Rider.”

“I’m having the greatest flashback vibes being here,” said Levy in reference to his appearance at Hall H two years ago to promote “Deadpool & Wolverine,” which became a massive hit. “I’ll never forget that night because it was also my real introduction to the greatest fans anywhere.”

Gosling greeted Marvel Studios chief Kevin Feige and told the crowd that he’d wanted to play the character for a long time.

Gosling’s longtime partner, Eva Mendes, starred alongside Nicolas Cage in Cage’s original standalone “Ghost Rider” film, released in 2007 — a year before “Iron Man” kicked off Marvel’s cinematic universe. A sequel was released by Sony in 2012, and film rights have since reverted to Marvel, but the character hasn’t appeared yet in the MCU.

Stars take stage for ‘Avengers: Doomsday’

Feige told the crowd that Joe and Anthony Russo’s 2019 film “Avengers: Endgame” will be re-released in theaters on Sept. 25 with new footage linking it to the Russos’ “Avengers: Doomsday,” due out Dec. 18.

A “Doomsday” trailer played during the panel showed that Robert Downey Jr.’s Victor Von Doom will have some past tie to Reed Richards (Pedro Pascal) and Sue Storm (Vanessa Kirby). Storm is seen saying that Doom is a broken person who used to be different: “Everything he loved was taken from him.” Later, Richards asks Doom if he’s the one responsible for the horrors around them.

Downey Jr. joked on stage that Reed and Doom were “besties.” Fans have been curious about the connection between the two after “The Fantastic Four: First Steps” post-credit scene included a clip of Doom sitting in Reed and Storm’s living room with their baby.

“Doomsday” stars taking the stage included Wright, Duke, Chris Evans, Hayley Atwell, Simu Liu, Danny Ramirez, Anthony Mackie, James Marsden, Kelsey Grammer, Paul Rudd, Rebecca Romijn, David Harbour, Lewis Pullman and Tenoch Huerta.

Ryan Reynolds appears as gray Deadpool

Clad in a new gray Deadpool costume, Ryan Reynolds crashed the panel from the audience.

“Longtime listener. First time caller,” said Reynolds, asking Rudd why Thor was crying in the previous film. Rudd responded “He’s a Wrexham fan,” in reference to the soccer team that Reynolds co-owns.

“This seems like an awfully expensive way to announce a film. When do you start filming,” asked Reynolds.

“It’s in the can, bro! Did you bump your head?” said Downey Jr. from the stage.

Many fans waited more than a day to get inside Comic-Con’s most-anticipated panel. Marvel Studios hopes it will act as a reset for its brand, which has been diluted by an overabundance of Disney+ series and critics’ disappointment in films like last year’s “Captain America: Brave New World.” Though audience interest in superhero films has waned in recent years, “Spider-Man: Brand New Day” — released by Sony in coordination with Marvel — is set to dominate the summer box office when it’s released July 31 and ticket pre-sales have been strong for “Doomsday.”
