Watch full length movies online for free. Visit either Hulu (hulu.com), Crackle (crackle.com) or OVGuide (ovguide.com). As of August 2012, all three sites provide free online movies, allowing you to browse or search by category or title.
Search for a movie title or browse through movie listings on each site to find a movie you might want to see.
Be aware that each site, since it offers its content for free, may offer mostly older titles and few or no new releases. In addition, each site typically interrupts movies with brief commercials lasting usually no more than 20 seconds.
Rent or purchase a movie to view online. Visit YouTube (youtube.com), Blockbuster (blockbuster.com), Amazon (amazon.com) or Vudu (vudu.com) and browse movie selections offered at various prices, usually no more than $5 per viewing as of 2012.
Download iTunes as another option, create an account or log in and search the iTunes Store for available movies. Be aware that iTunes, YouTube and Vudu give you the choice to either rent or purchase certain titles.
For rentals, be sure to finish watching the movie within the time specified, 24 hours for most sites. But also consider Netflix, which lets you watch unlimited movies from its selection, for about $8 per month, as of 2012.
Watch movies online through your cable television or Internet provider. Check with your provider to see if it offers Internet-streamed movies to watch on demand.
Visit your provider's website and log in to your account if you have one; otherwise, create an account and then log in.
Select a movie from the on-demand titles available, and then follow additional instructions. Most likely any charges, if imposed, will simply be added to your monthly bill.
