I kinda get the impression the Ewan McGregor intends to drop enough rumors of an Obi-Wan movie that eventually the studio will have no choice but to make one. Like, he basically is going to show up at the studio one day in full costume with a handful of friends, possibly even a script in his hands, and just say 'hey, we're ready to film, let's get to work!' while a studio exec just stands there with a very confused look on their face.
Marth, honey, are you so sure about this? Perhaps you have the advantage of distracting Ike? Or an alternative way out? After all, I do remember a post that said if you know you're going to lose an arm wrestle, just lean forward and kiss your opponent.
