Yeah, so there’s going to be a G.I. Joe sequel.  And that’s apparently such a minor and unsurprising news item that the LA Times all but breezed through it in a longer article about box office grosses:

[G.I. Joe's box office was] certainly good enough for Paramount to claim victory, however, and start thinking about the future. The studio’s vice chairman, Rob Moore, confirmed that a sequel will soon go into development. The film’s lead actors are contractually obligated to return for another film, though director Stephen Sommers is not.

Well I hope Stephen Sommers doesn’t ask for too much money, and can find time in his schedule between The Mummy 6 or The League of Extraordinary Werewolves or whatever.  Otherwise, I don’t know what could happen to this franchise.  But as long as Channing Tatums is there to mumble and stare vacant eyed while Marlon Wayans slips on banana peels I’m sure everything will be fine.
