There is no way to stream Disney movies online for free. However, Disney's streaming service, Disney Movies Anywhere, allows users to purchase Disney films and stream them to mobile devices and personal computers, as of 2015.
Disney Movies Anywhere was launched by Disney in 2014, and features a wide array of Disney films, including films from Pixar and Marvel. The service requires users to create an account, which allows them to purchase and customize their Disney film collection. Disney movies can also be purchased from digital services such as iTunes and Amazon Instant Video. However, these services do not have as large a selection as Disney Movies Anywhere.
