San Diego Comic-Con 2026: Marvel, HBO, and Middle-earth collide

San Diego Comic-Con is about to get very crowded. Marvel's Avengers: Doomsday and HBO Max's Lanterns are headlining the event, but the real draw is the slate of exclusive previews and cast panels happening across the weekend.

We'll follow the live coverages and livestreams, capturing exclusive reveals and interviews as they happen. If you've been waiting on any of these projects, SDCC is where the first real footage and behind-the-scenes intel will drop.

Here's what's worth tracking: Percy Jackson and the Olympians Season 3 hits Disney+ on November 20, and Comic-Con will get the first exclusive look before anyone else. The Blade Runner 2099 panel brings cast and executive producers to talk about the 2027 premiere. Over on Amazon Prime, The Lord of the Rings: The Rings of Power Season 3 arrives November 11, with exclusive previews premiering at the convention.

It's the kind of weekend where every panel slot matters and the livestreams will be essential viewing for anyone tracking what's actually coming next in prestige TV and tentpole film. SDCC remains the place where studios still move the needle on hype.
