Isla Fisher is in talks to join the cast of director Baz Luhrmann's 3D adaptation of the classic novel The Great Gatsby.

The actress will take on the role of Myrtle, a married woman having an affair with Tom Buchanan, a role that Ben Affleck is currently in negotiations for. Leonardo DiCaprio will be playing Jay Gatsby, with Tobey Maguire set as Nick Carraway, and Carey Mulligan playing Tom Buchanan's wife Daisy.

It's not known when Baz Luhrmann will begin shooting The Great Gatsby, but it should happen later this year with a release planned for 2012.
