To be honest I'm not entirely sure. I saw the trailer for it the other day and all I remember seeing on it was clips of Planet of The Apes (again) and Batman films. I'm sure there were a few more in there but it was just the usual films they tend to show anyway I think, nothing spectacular or out of the ordinary. A missed opportunity.
I've looked on the channel 4 website and theres no info on the sci -fi season, unless I missed it.
I've checked wiki, apparently they had a sci-fi season last year too, I vaguely remember that, heres the list from that -
Sci-Fi Season (2008)
This season showed triple bills of Sci-Fi films for two weeks, taking up the 7PM, 9PM, and 11PM slot.
* 20,000 Leagues Under the Sea
* The Abyss
* Beneath the Planet of the Apes
* Fantastic Voyage
* The Fifth Element
* Cypher
* Star Trek Nemesis
* Fantastic Four
* Jason X
* Memoirs of an Invisible Man
* The League of Extraordinary Gentlemen
* Big Trouble in Little China
* Explorers
* Alien vs. Predator
* Alien
* Predator 2
* The Core
* Underworld
* Sky Captain and the World of Tomorrow
* I, Robot
* ThunderbirRAB Are Go
* Conquest of the Planet of the Apes
* Timeline

A few classics in there but it's mostly standard stuff. I guess we'll be getting repeats of these (with a bit of Batman of course). Ho hum.
