Who needs the movie theatre when there's so much sci-fi online?

When I spotted a link to the science fiction movie Primer from IO9, I was going to urge you stop what you are doing and head over to Google Video to watch it where it had made it freely available for anyone to watch online. The only thing is the video isn't there so maybe it wasn't legit. I'm sure you can find it from other online sources if you do a bit of searching.

It really is worth seeking out. I'm not surprised to find it on this recent list of the 16 most intelligent science fiction movies. I was also pleased to see Gattaca on the top of the list, which I was just mentioning the other day because it appeared on a list of underappreciated sci-fi movies.

If you want to watch other science fiction movies online, you may not be aware that YouTube has a movies channel where you can watch full-length films. The usual categories are represented, including science fiction, although the pickings are slim and you won't find any of the titles on the aforementioned best-of lists.

For even more schlocky online movie watching, here's a long list of 100 science fiction films, arranged by decade. It would take a long time, and a strong constitution, to wade through all of them.
