Interesting, my wife is a Sci-Fi nut, take it as read that if you were to ask her anything about any character or plot line in any Star Trek or Star Wars episode/film she'd be able to tell you without thinking about it (the later Star Wars stuff she won't know, she's not a fan of the the stuff Disney are pumping out)... she's also a huge Babylon 5 (or as i call it, babbling dive lol) diehard, i love Sci-fi as well but B5 is just odd, that said i did love Mollari the character, mostly because i was forced to watch nearly every episode as she recorded them to VHS from live TV!
As for Dune, i don't know why but it's never been a film i've watched, possibly because it's based on a game and i'm not a big gamer and it put me off watching it on that basis?
I don't know if she's read the book (probably has if i know her at all) but i know she watched the first film and she just recently watched Part 2 and she loved it.
As an aside if you're into motor racing, i love F1 and came across this insight into the yet to be released still being filmed Brad Pitt F1 movie (called "F1") that's kind of a behind the scenes look but not from the production company, rather it's from a journalist (i think?) who has access to the F1 pitlane.
I obviously won't know if the film will be any good until it's released but this is a very interesting insight into how the film is being filmed, it's somewhat eye-opening if your into filming methods and behind the scenes stuff.
