From star-studded panel discussions to exclusive swag and never-before-seen film footage, Comic-Con International is an annual must for swarms of die-hard fans and industry insiders alike (last year, roughly 130,000 attended the multi-day event). And if the rumblings on the interwebs are to be believed, this year's convention will be bigger and badder than ever.

Beginning July 18 (that's tomorrow) through Sunday, July 21, fan favorites and sci-fi newbies alike will descend upon San Diego for a four-day, all-out extravaganza of panels, screenings, workshops and so, so much more.

With so much happening, it's easy to miss something. Especially since we're told it's next to impossible to be in two places at once. So, while you should definitely scroll through a complete schedule of Comic-Con events, here are a few highlights of the best, not-to-be-missed events happening from our colleagues at Warner Bros., Turner and HBO. (And if comprehensive coverage is what you're looking for, be sure to check out the Comic-Con section of Entertainment Weekly's website.)

Warner Bros.

Life-size blow-ups of Cartoon Network's Teen Titans Go! to life-size LEGO creations of Bag End, Bilbo's underground home from The Hobbit: An Unexpected Journey are not to be missed.

All in all, DC Comics has more than 15 panels throughout Comic-Con. Not to mention a display of seven Justice League-inspried KIA cars featuring artwork from legendary artist Jim Lee (not the first time DC Comics and Kia have joined forces).

And we can't forget about all the sweet (read: exclusive) swag that comes with attending Comic-Con. For the fourth year in a row, Warner Bros. Entertainment is the title sponsor of the official bag of SDCC 2013. And this year, it's not just a backpack. It's also a cape. Attendees will get one of a variety of backpacks featuring a WB title (like Revolution or The LEGO Movie), filled with copious amounts of swag and a detachable Super Hero cape (see images below).

Fans that swing by the WB booth will also get a free copy of the Warner Bros.-themed, Comic-Con edition of TV Guide Magazine. Featuring four sets of collectable "flip" covers, the 88-page special issue is packed with exclusive photos, previews and more.
