The following is a list of President Obama's seven essential science fiction films/series as appearing in a special Issue of Wired he guest-edited. It is arguably the most white bread list any person could come up with, which make sense because I assume Obama had his top people on it.
2001: A Space Odyssey
Close Encounters of the Third Kind
Star Wars: A New Hope
Star Trek (The Original Series)
Cosmos: A Personal Voyage
I'm assuming numbers 8 - 10 were Alien, X-Files and The Twilight Zone or Doctor Who. I mean, I guess these are essentials, but they're like, so essential there's no way anybody hasn't seen them. I wouldn't even classify these as sci-fi essentials, they're just essential essentials. Except The Martian, that was just okay.
Thanks to Andy TA, who agrees The Abyss and Cocoon should have made the list.
