Open Culture is a site that directs you to all manner of content you can get for free.

We're talking ebooks, audio books, textbooks, online courses, language lessons, kids' stuff, and movies. You can study thermodynamics, marine megafauna, Scandinavian film and television, robots, drugs and addiction, cryptography, and archaeology.

You can watch silent movies by Andy Warhol, Wes Anderson's first short, a biopic on Caravaggio, Rashomon, Orson Welles' Nazi-hunter movie The Stranger, and Sex Madness, the movie that is to sex what Reefer Madness is to pot.
