Okay, I realize some of my choices may cause some people to question my sanity. And how I rank them. But remember, these are my favorites, not what I think are the best. That would be a totally different list -- this is about the ten sci-fi movies I love the most and how often I watch them. Keeping that in mind... feel free to disagree with me :-)
1. Serenity (2005)
Captain Mal Reynolds (Nathan Fillion) and his band of smugglers (Alan Tudyk, Adam Baldwin, Summer Glau, etc.) take on an Alliance assassin to protect one of their own and wind up uncovering a vast conspiracy. I saw this on the big screen and have been a Browncoat ever since.
2. Return of the Jedi (1983)
Luke and Leia rescue Han, Luke and Han rescue Leia, Lando and R2-D2 rescue everyone at once... and that's only the first sequence, which happens to be my most favoritest. I've seen the first 40 minutes of this more often than any other segment of any Star Wars movies.
3. Independence Day (1996)
A pilot (Will Smith), the President of the USA (Bill Pullman), and a variety of other humans band together to save earth from an alien invasion. I love how it mixes serious, exciting, and funny together so seamlessly.
4. A New Hope (1977)
An idealist (Mark Hamill), a princess (Carrie Fisher), a smuggler (Harrison Ford), and an aging hero (Alec Guinness) help the Rebel Alliance take out the Empire's greatest weapon. What can I say about it that hasn't been said a billion times before?
5. I, Robot (2004)
A robot-phobic policeman (Will Smith) reluctantly joins forces with a robot (voiced by Alan Tudyk) to stop a robot uprising. Sleek and smashing.
6. Equilibrium (2002)
A law-enforcement officer (Christian Bale) takes on the regime that has outlawed all emotions. Imagine if The Matrix had been written by Ray Bradbury. I just wish Sean Bean was in more of it.
7. The Empire Strikes Back (1980)
Luke learns the truth about his parentage, Han and Leia try not to fall in love, and the Empire tries to figure out what hit them. I like half of this movie a lot, and am bored by the other half.
8. Bill & Ted's Excellent Adventure (1989)
Two melllow high school students (Keanu Reeves and Alex Winter) travel through time to collect info so they can finish their homework and save the future. Smarter and funnier than you expect.
9. Sky Captain and the World of Tomorrow (2004)
A pilot (Jude Law) and a reporter (Gwyneth Paltrow) try to figure out why there are giant flying robots attacking New York City. Retro and gorgeous and fun.
10. Back to the Future (1985)
Marty McFly (Michael J. Fox) uses Doc Brown's (Christopher Lloyd) time-travelling car to go back to the 1950s and make sure his own parents get together. Classic and wonderful.
