In the two years(!) that Science Fiction 101 has been running, we've somehow managed not to ever list our favourite movies. Until now. But faced with an almost impossible task, we choose two different methods of revealing them: Colin goes for the top ten (or top nineteen...) countdown; while Phil opts for a chronological approach.

Which films did we choose? Are there any films common to both Colin and Phil's lists? Join us, and find out.

And do, please, let us know your favourites. You can do that by leaving a comment on our blog at 101sf.blogspot.com - or by finding us as Science Fiction 101 on Facebook.
