All change for Baz Lurhmann’s big screen 3D adaptation of F. Scott Fitzgerald’s The Great Gatsby as a long rumoured cast member walks away while any saunters in.

e Affleck’s name has been floating around the project for a while now and he was rumoured to be set to star as Tom Buchanan, and now Deadline report that his directing duties on the film Argo prevent him from taking on both jobs.

Argo will be Affleck’s directorial follow on from the well received 2010 movie The Town and will tell the true story of the rescue of six US diplomats in 1979 Tehran. The film is based on Joshuah Berman 2007 Wired article, “How the CIA Use a Fake Sci-Fi Flick to Rescue Americans from Tehran” and is said to have George Clooney on producing detail.

So, Affleck is out and a new Tom Buchanan is sought. Whoever it is they’ll have a rising star on their arm as THR are reporting that Isla FIsher is in talks to star as Buchanan’s mistress, Myrtle, who has a crucial part to play in the story. Fisher was recently in John Landis’ Burke and Hare and Confessions of a Shopaholic and you’d be hard pressed to find anything to compare with the dramatic scope she’ll have on take on if she is offered and accepts the role.

Leonardo DiCaprio, Carey Mulligan and Tobey Macguire are all set to star in the production.
