Netflix have, for some time, had a great deal with Disney (including Star Wars and Marvel) even securing the first rights to online streaming of their movies. Netflix across the globe has always, until recently, had a good selection of Disney movies. In the UK, Netflix lost nearly all it’s Disney content when Disney Life launched at the end of 2015 but the deal in America stayed in place.
However, according the The Verge this deal will be ending in 2019 and Disney will be launching their own streaming service, presumably Disney Life like in Europe. Netflix should see Star Wars Episode 8 and the Han Solo movie arrive but after that it is highly unlikely for any major Disney titles to be added. The Marvel TV series, like in Europe, will not be affected. Disney Life tends to cater to the younger viewers so 18 / R -rated TV shows won’t be an issue.
