The world is not built to accommodate such subtle flawlessness. One who can be so intelligent and thoughtful and dorky and humble and gracious and charming is not by nature intended to be also in command of such fine looks and quick wit. The ways of the world dictate that a being of such blissful personality should be condemned to eternal acne and sprawling limbs that dangle around one's person like an ill-fitting Christmas Cardie. James McAvoy is an aberration. The universe has adapted to cope with him, but multiple would be a disaster.
That is what you have done. The universe short-circuited and expelled his various embodiments into the world in which he lives. It is vital that this error be rectified within the month or the consequence shall be the total destruction of the fact that James McAvoy ever existed. His parents will deny ever having given life to him, his wife will deny ever having married him, his friends and directors and screenwriters and everybody he ever met, spoke to or influenced in any way will be unaware of his ever having lived. Because he will not have. His son, too, will cease to have any bearing in the world.
It has fallen to you, the culprits and the characters to put right this overload. You must travel to the homes of each character that's been ejected, fictional location or otherwise. All must be accomplished for the Universe is proud to boast James McAvoy, and, if he is lost, a terrible sadness will fall upon the world, though nobody shall know why. Plants will wither and crops will not grow and humans will begin to lash out at each other at the slightest provovation. The world will not die, but it shall be a gloomy place to live.
Brian Jackson turned to Joanne with a grin of delight on his face.
"That was so cool!" he declared.
"Yes, yes it was," Joanne agreed, baffled by the sudden revelation that cynicism was futile.
"Who's this James McAvoy everyone's going on about?" Brian knitted his eyebrows.
"He's ... an actor."
"I've never heard of him."
"I'm not surprised."
"What's he look like?"
"You."
James had taken quickly to the situation and Joanne guessed that was his tendency to take evidence without dispute, to believe anything so long as it was proven to him. The simple fact of what he'd experienced had been enough to convince him of the truth. He did not however understand his peril, his grave, grave peril of utter obliteration.
"Brian," Joanne murmured, "There's something you should know."
She picked up the case for the 'Starter For 10' DVD and showed him the picture. It was a photograph of the day he'd messed up. In fact, he didn't ever remember it having been taken but he'd tried desperately to rid his memory of everything that day contained, except the knowledge that whatever he'd done, he'd do it differently next time. Brian spotted a name printed in black above his head and nearly joked on his very flat 'Irn Bru', a drink he'd heard of a few times before and had convinced him he truly was somehow in Scotland.
The name was James McAvoy.
"He does look like me!" Brian gasped, "Why's he look exactly like me?"
"Because he ... played you."
"You mean they made a movie about us? I never even knew."
"Well, you wouldn't, considering this movie was made in 2006. Or 2007, I can never remember."
"The 21st century! But it's 1985! Did I TIME TRAVEL?!"
"Evidently," Joanne murmured, "Look, nothing about this makes any sense but this is going to be hardest. Ready?"
"No, but go on."
"You are fictional."
