Miscasting Hall of Fame!
Just saw this again, on one of the Mesothelioma Channels when I couldn't sleep. And I hate to say this, because a friend was an extra in this movie and thinks fondly of it, but the movie sucks - largely because all the major roles were miscast!
Redford's usual schtick of sitting back and letting the audience come to him doesn't work here, Gatsby needs to have an aggressive, superficial charm, and a deeper, more vulnerable charm underneath... and Redford displays no charm at all. Sam Waterston is to mature and knowing for the role of Nick, Nick should be somewhat innocent, easily swayed and easily seduced, in love with the glamour around him. And the role of Daisy is impossible, the camera sees through her long before the audience should, but Mia Farrow is neither beautiful enough nor upper-class enough to even attempt the role. And her voice is whiny, she's irritating rather than beguiling.
Really, the 2013 version is far better, even if it's not really a successful film.
