Is it illegal to watch free movies online that are still in theaters?

It is somewhat illegal but you won't get in trouble for it. If you download the movie you can get in trouble for it. I have had it happen before. My internet company shut off our internet and told us we had to delete the movie and not do it again, but if you are just watching the movie on a website the website will get in trouble not you. They can easily track your downloads but it's a pain in the butt for them to track the movies you just watch on websites so they don't even bother.
