A while back, we told you that Zodiac scribe James Vanderbilt has been hired to pen the script for Spidey 4, but as of right now, the leads -- Tobey Maguire, Kirsten Dunst, and James Franco -- haven't been confirmed yet to star in the film (though something tells me Franco won't be returning for "certain" reasons). That got us thinking ... what if Tobey Maguire decided to move on from playing the Webbed One? Who else could fill that Spidey-suit? Would it be best to go for someone close to Maguire in physical type, or try something completely different? From High School Musical hottie Zac Efron, to boy-wizard-and-more Daniel Radcliffe, from the "superbad" Michael Cera to the multi-talented Elijah Kelley ... who could you see taking on the role of Spider-Man if Maguire decided to retire from the role?
