Jamie Foxx, the 'Twilight' cast and the stars of 'Community' also make the list
Robert Downey Jr.
Name: Robert Downey Jr.
Comic-Con Virgin: Are you kidding? Robert Downey Jr. is the king of Comic-Con.
Promoting: "Iron Man 3" and most likely "The Avengers 2"
When: Saturday, 6:00 - 7:00, Hall H
Lowdown: There are very few people who know quite how to rock the stage of Hall H the way Downey does, and with "The Avengers" at $600 million and counting domestically, this is as much a victory lap as a promotional appearance. He loves the Comic-Con crowds, and they love him, and if he's able to actually bring footage from "Iron Man 3" (Marvel has a long history of putting together product reels at faster-than-possible speeds), there's a good chance he's going to shake the foundations of the Convention Center with the sustained group nerdgasm that will ensue.
