A shimmering, crystalline portal opening to a blocky, fantastical world.

The ad opens with a shimmering, crystalline portal revealing a fantastical, blocky landscape reminiscent of Minecraft. Jack Black appears, looking amazed, and then begins interacting with the blocky world, building and exploring. The scene transitions to a group of children and Jason Momoa also exploring this world. There are quick cuts of action, including an explosion and a battle with pig-like creatures. The title card for 'The Block Party' appears, followed by 'A Minecraft Movie'. The ad concludes with the HBO Max logo and subscription offer.
