Seek out websites that offer movies for free. Use them with care, however. Some sites, like SurfTheChannel (surfthechannel.com), are merely indexes that link your computer to movie-offering websites. These have been known to distribute computer viruses and malware. Other sites, like Hulu (hulu.com), are supported by ads and allow you to view copyrighted films.
Pay to download a movie you want to see through an online content service. One of the best known of these is the iTunes store (apple.com/itunes/charts/movies). Through iTunes you can either buy an electronic copy of the movie or rent it for a limited time. The fees are about what you would pay to buy or rent a movie at a bricks-and-mortar store. Blockbuster (blockbuster.com/download) offers similar on-demand films.
Subscribe to a service that streams movies, TV shows and other video content to your computer or cable television. Companies like Netflix (netflix.com) offer monthly subscription plans that allow you to view an unlimited number of movies each month.
