Some of the most reputable sites that offer free movies include Crackle and Hulu. Both of these sites offer streaming service without dangerous malware, excessive ads or other undesirable features.
Crackle is one of the most popular free movie sites online due to its lucrative partnership with Sony Pictures. The agreement between Sony and Crackle allows site users to stream a large selection of popular Hollywood films free of charge. The site does feature some ads during movies, but the interruptions are minimal.
Hulu offers a variety of free movies and TV shows. Users can upgrade to Hulu Plus to watch movies in HD, but the free streaming service allows access to a range of films.
