Comic-Con 2010 Preview: 'Green Lantern,' 'Harry Potter' And More

Seth Rogen, casts of 'Thor' and 'Scott Pilgrim vs. the World' expected to give talks and sneak peeks.

Fluff the fur on your Wookiee costume. Put the final touches on that homemade Wonder Woman outfit and make sure your Batman suit isn't that embarrassing one with the nipples on it. That mecca of pop-culture geekery known as San Diego Comic-Con is once again upon us.

The festival kicks off with a preview on Wednesday evening (July 21), followed by four-straight days of sneak-peek looks at celebs, movies, comics, games and much more. MTV News will be right in the thick of the madness, bringing you daily live-streams from the Con.

Get ready for heady chats with Seth Rogen ("The Green Hornet") and Robert Rodriguez ("Machete") on Thursday; the casts of "Tron: Legacy" and "Scott Pilgrim vs. the World" on Friday; and lots of surprise appearances on Saturday.

Of course, we'll also be bringing you fresh scoops from the convention — the latest news on some of the most anticipated Hollywood films. Here are some of the movies we can't wait to check out:

"Green Lantern": Saturday at 11:45 a.m. PT

Saturday marks the kickoff of Warner Bros.' blockbuster presentation in Hall H, and there's little doubt "Green Lantern," based on the DC Comics property, is the studio's most eagerly awaited flick. Coming on the heels of a first look at Ryan Reynolds as the titular superhero, fans have been promised the first-ever glimpse at actual movie footage. There's no official word that Reynolds will be in the house, but we're going to go ahead and predict he'll make an appearance.

"Tron: Legacy": Thursday at 11:15 a.m. PT

This sequel to the 1982 sci-fi classic has appeared at three straight Cons. After premiering test footage in '08 and a more robust video in '09, you can now expect Disney to deliver a hefty look at the new film, which arrives in theaters in December. Castmembers expected to attend include Jeff Bridges, Olivia Wilde, Garrett Hedlund and Michael Sheen, as well as director Joseph Kosinski.

"Harry Potter and the Deathly Hallows": Saturday at 11:45 a.m. PT

Anything having to do with the boy wizard shoots immediately to the top of many Con-goers' wish-lists. This year, Warner Bros. will debut fresh "Deathly Hallows" footage, as the studio pushes toward opening the first part of this series' finale in December. No castmembers have been announced, but there's always a chance someone from Hogwarts might stop by to greet fans.

"Thor" & "Captain America: The First Avenger" Saturday at 6 p.m. PT

We've been checking out concept art and photos for both these Marvel adaptations, but who knows what we'll get at the Con? "Thor" has been shooting since early this year, while "Captain America" just began production last month. Will we get footage from either flick? Let's wait and see. We do hear "Thor" stars Chris Hemsworth, Natalie Portman and Kat Dennings will be at the Con, and we're also hoping to see Captain America himself, Chris Evans, drop in on the festivities.

"Scott Pilgrim vs. the World": Thursday at 6 p.m. PT

In the midst of the Marvel and DC behemoth is "Scott Pilgrim," a graphic novel series that started out as an indie hit and has now graduated to the mainstream. Clips and trailers have been lighting up on the Web for months, so who knows how they'll step it up for Con fans. We expect, somehow, they will. Michael Cera, Mary Elizabeth Winstead, Brandon Routh and Jason Schwartzman will be on hand, as well as director Edgar Wright and series author Bryan Lee O'Malley.
