Muses Deadline, "Shane is first and foremost a writer but it's not clear whether he'll be penning the IM3 script as well. 'That's not figured out,' our source says. Of course, everyone in and around Marvel is keeping mum. But Black has a long relationship with Robert Downey Jr since Kiss Kiss, Bang Bang. Not only did Shane make his directing debut on the 2005 cult favorite he co-wrote, but it helped re-launch Downey Jr’s career. When news leaked out that Marvel was meeting with several directors including Shane, fanboys approved. So they should exult now that negotiations are wrapping up with Black's agency WME and manager David Greenblatt's GreenLit Creative."
Black, who created Lethal Weapon, has also been working on movie versions of pulp hero Doc Savage and the Manga, Death Note. No word on where those projects would fall in his schedule if he was brought aboard Iron Man 3.
