What a year it's been for comic book adaptations. From Bullet to the Head in February to Thor: The Dark World last month, Hollywood's big names have spent hundreds of millions making comic book movies in 2013. Next year brings at least eight more scheduled adaptations. Which studios own the characters that will pay off most for investors?

Fool analysts Tim Beyers and Nathan Alderman tackle the big properties in latest episode of Geekstock, The Motley Fool's new Web show, in which Tim, Nathan, and host Ellen Bowman introduce you to the big-money names behind your favorite movies, toys, video games, comics, and more.

Nathan says Twenty-First Century Fox (NASDAQ:FOXA) could enjoy gains now that the studio is working on a building a bigger and more expansive universe around the X-Men, including next May's X-Men: Days of Future Past and the just-announced X-Men: Apocalypse, which is due in theaters in 2016. Meanwhile, efforts to include The Fantastic Four in the studio's own version of a shared Marvel Universe are still in development.

Tim says that Sony (NYSE:SNE) has what amounts to an all-in bet on its rights to Spider-Man films. The Amazing Spider-Man 2 is due in theaters on May 2 of next year. Future sequels are planned for 2016 and 2018, though Sony also has plans for spinoff movies centered on Spidey's villains, such as Venom and the Sinister Six. And while the guys don't talk about it during the episode, Time Warner is also making big bets on its DC universe of characters.

Still, if there's a company to bet on, both Nathan and Tim say it's Walt Disney (NYSE:DIS). The studio, which already has film rights to the vast majority of the Marvel Universe of characters, recently bought the right to make new Indiana Jones films from distribution partner Paramount. That's a potentially huge win for the studio.

Meanwhile, Ellen teases some of the amazing holiday swag available at ThinkGeek while putting both Tim and Nathan on the spot.
