I see Film 4 are running a sci-fi season, (is Batman really sci-fi?). Anyway, I'm not particularly looking forward to their selection but here's what I'd have rather seen.
My top ten sci-fi films
(In no particular order)
1. The Thing
2. Blade Runner
3. Alien
4. The Fifth Element
5. THX 1138
6. The Andromeda Strain
7. Invasion of the Body Snatchers
8. Sleeper
9. Metropolis
10. The Empire Strikes Back
The original is arguably better than the intense remake.However,you would need to look beyond the fact it's B&W,has silly makeup/effects,and has an highly impractical plot.
Is Eternal Sunshine of the Spotless Mind sci-fi? I've seen it billed as sci-fi before but never quite sure whether to agree with the label. I guess they use some advanced technology, so...
Anyway, if it is, I think it definitely deserves a place.
