Heat Vision is reporting that Baz Luhrmann’s film version of The Great Gatsby is one step closer to filling out its principle cast. Most of the main roles have already been grabbed up at this point, and by actors that fit the bill pretty nicely; but this latest news gives me pause. Reportedly Isla Fisher is in negotiations to join the cast as Myrtle Wilson. Leonardo DiCaprio is playing the charming and mysterious Gatsby, which makes sense because of DiCaprio’s leading man looks. Tobey Maguire is playing the film’s everyman narrator Nick Carraway, which makes sense because everyone already thinks of him as the ultimate everyman Peter Parker. Carey Mulligan is playing Daisy Buchanan, which makes sense because Mulligan can do anything, and being a rich white girl is probably something she can pull of in her sleep. Ben Affleck was playing Tom Buchanan, which made sense because Buchanan is a jerk that cheats on his wife and slaps ladies around and, love him or hate him, you have to admit Affleck naturally projects a bit of that doucher vibe that would fit the character perfectly. However, Deadline East Egg is reporting that Affleck has been locked to direct and star in Argo, and won’t be available for Gatsby. And now Isla Fischer is playing Myrtle Wilson, the frumpy, plain, wife of a mechanic, which makes sense because, uh… I got nothing. I sure like looking at Isla Fischer though, so good news all around!
