Leonardo DiCaprio and Tobey Maguire arrived on the set of The Great Gatsby in Sydney today. The actors are getting started on the film adaptation, which will also star Carey Mulligan and Isla Fisher, now that the casting details have all been sorted out. Ben Affleck was originally in talks for a part in the movie, though he dropped out to pursue his latest directorial project, Argo. Leo made his way Down Under after spending the weekend in LA with girlfriend Blake Lively. Leo and Blake grabbed lunch at Umami Burger and shopped at Fred Segal during Blake's lunch break from filming Savages. Tobey, meanwhile, has been busy with his family and spent much of the Summer hanging out near home with his wife, Jennifer Meyer, and kids, Ruby and Otis.
