A book-to-audiobook phenomenon called 'Dungeon Crawler Carl' emerged as an unexpected centrepiece at this year's San Diego Comic-Con. The series, which reimagines Earth as an alien video game competition, has sold more than 10 million copies and is being adapted into a live-action show for Peacock. At the convention, author Matt Dinniman and the audiobook's narrator—who performs over 200 distinct character voices—confirmed that the narrator will voice Princess Donut, a key character in the television adaptation. Dinniman also expressed ambitions to expand the universe into gaming formats, including a potential MMORPG.

Marvel Studios dominated Hall H with casting announcements and exclusive footage for 'Avengers: Doomsday,' featuring Robert Downey Jr.'s return as Doctor Doom alongside numerous major franchise actors. The studio also revealed that Ryan Gosling will headline a Ghost Rider film and that a new actor will portray the successor to Chadwick Boseman's Black Panther character. In contrast, DC Studios took a more restrained approach to the convention, focusing its Hall H presentation on the upcoming 'Lanterns' detective-focused Green Lantern series rather than announcing fresh projects.
