Potential talent: James Franco, Mila Kunis, MIchelle Williams, Zach Braff, director Sam Raimi
Why:  Disney's pricey update of L. Frank Baum's world of Oz doesn't come out until next March and there hasn't yet been any promotion; Comic-Con could be the first big coming out for the risky venture. Director Sam Raimi still has a surplus of Comic-Con goodwill leftover from the first two "Spider-Man" films (let's just forget the third) and the "Evil Dead" series. With both those franchises currently in the hands of other directors, now's the time for Raimi to re-establish his cred with a new take on a beloved property. Throw in fan favorites James Franco and Mila Kunis, and it's a hard-to-resist package for attendees.
Chances of happening: 75%
