Close Encounters + 17 more sci-fi movies you can watch online for free

Close Encounters of the Third Kind

Steven Spielberg’s classic has inspired a generation of sci-fi fans, and now you can watch it for free with your kiddies (or get reacquainted just for fun).

With so many services out there vying for our hard-earned money, it’s easy to forget there are still plenty of sci-fi flicks you can watch for free. So what’s the cream of the crop (and where can we find it)?

We expect services like Netflix to have an ample supply of good sci-fi (hey, you’re paying for it!), but some free services can also scratch that alien and comic-book itch if you’re not ready (or able) to drop some cash.

From Hulu to Crackle to the Internet Archive — there’s a lot of stuff to find out there if you know where to look.

So what are some free sci-fi flicks we can stream to keep us busy during this hot, lazy summer?
