I found this website recently. You can watch all sorts of movies! Even the new releases that are still playing at the movies. For some movies the quality isn't the greatest.. But hey, it's free! What more could you ask for?

There's also this website..

It has movies, tv shows, music etc. The first link has a bigger database though.
Enjoy!
