The iPod in his hand is not an anachronism, Maguire is just on his way to the set. The first two images come from CeleBuzz, while the second two originated at NY Mag's Vulture. While the first three images are Tobey-centric, the last one shows an exterior set in Sydney, representing Long Island in the early 1920's.
This project is a reunion between Luhrmann and his Romeo + Juliet Romeo Leonardo DiCaprio, who is playing none other than Jay Gatsby, old sport. The duo attempted for some time to get an Alexander the Great epic underway, but that fairly well fell apart when Oliver Stone's Alexander came together first. Carey Mulligan co-stars as Daisy Buchanan, the object of Jay's misguided affections, and Joel Edgerton will play her racist, polo-loving husband Tom. Isla Fisher and Jason Clarke round out the cast as Myrtle and George Wilson.
