Isla Fisher is in talks to play Myrtle in Baz Luhrmann's star-powered The Great Gatsby. If talks don' break down into Fisher holding her breath until she gets her way, she'll join the previously cast Leonardo DiCaprio, Tobey Maguire, and Carey Mulligan.

DiCaprio is playing Gatsby, Maguire will play Nick Carraway (the book's narrator), and Carey Mulligan will play Daisy Buchanan, a woman torn between her love for Gatsby and her boorish husband, Tom Buchanan. Ben Affleck has been approached for Tom, and if cast, Fisher will play his mistress. This is odd casting. Myrtle wasn't this hot or young in the book. I saw her as more of a Christina Hendricks, but Fisher is a welcome addition to this cast. The only way to settle this is to have those two fight it out in my mind. To the Jelly Pit!! (THR)
