Following up on a previous entry: it is legal to download Gatsby in every country except for seven. The United States is one of those seven.
If you happen to live in a country other than those seven – say, for example, Australia – it is perfectly legal for you to download Gatsby from the local version of Project Gutenberg.
Also, I wanted to link to this week’s episode of “The Ihnatko Almanac”: (Edited to add: Fixed. Thanks, Lawrence.) Andy Ihnatko touches on Baz Luhrmann and Gatsby, though his primary topic is one we brought up the other day: Sebastian Faulks continuing the Wodehouse Jeeves novels.
(I also wanted to link this because if you listen to the first couple of minutes, you’ll hear a name you might recognize.)
(Important safety tip: be careful who you page, and who you send feedback to. They just might read your name on the air. Not that there’s anything wrong with that…)
