Gandalf (or if you want to be all serious) was on The Jonathan Ross Show this past weekend where he announced that he would be officiating 's wedding. The thoughts and feelings upon hearing this are as follows:
The only way this could possibly get any better is if they went as Magneto and Professor Xavier. Stewart's new wife wouldn't be weirded out at all. The world would join hands: Humanity United, The Last Stand. would be the flower hobbit, and the most epic mutant dance party to ever grace the world would cause all sentinels to stop what they're doing and take Bolivar Trask on a much needed vacation so he'd get a grip and stop being such a buzzkill.
Congratulations to Stewart's upcoming nuptials and for having McKellen as such an amazing friend.
