YOU KNOW WHO'D BE PERFECT FOR COURTNEY? ANYONE BUT COURTNEY: So, they're going to make a movie about Kurt Cobain - Mel Gibson could direct, Everett True will be shown the final cut and utter a gnomic "It is as it was." But what about the casting? We know there's going to be an unseemly catfight between Jessica Simpson and Britney Spears for that plum Courtney role. And we suspect the reason Todd in Corrie has been growing that Banardos Charity Shop Beard might be out, then - although who's to say that Matthew Perry, now free from Friends, might not fancy bringing his perspective ("I know the pain of addiction") to the Kurt role. Jack Black for Tad, anyone?
