With the constant uncertainty on whether or not Tobey Maguire will return for a fourth Spider-Man film, website Cinema Blend is reporting from a "reliable, proven, inside source" that The Lookout's Joseph Gordon-Levitt is in contention as a possible replacement for Maguire if he decides not to return as the web-slinging hero.

Spider-Man producers have been quoted as saying they would continue with the franchise with or without Maguire and have approached original Spider-Man writer David Koepp to pen a script for a possible fourth outing.

In addition to his critically acclaimed role in The Lookout, Gordon-Levitt is probably best known for his role on the long-running NBC hit 3rd Rock from the Sun.
