But the new service is being launched with reduced bandwidth - and hence output quality - because of the heavy demand on network infrastructure during the coronavirus crisis.
After its USA launch last November, Disney is now streaming in Ireland, Austria, Britain, Italy, Germany, Spain and Switzerland. Its library is full of hit titles from Disney, Pixar, Marvel, all the Star Wars franchise, and National Geographic.
Disney+ launches in the United Kingdom from tomorrow and Samsung has just announced that this new streaming service will be available on their range of Smart TVs.
But the option of a 7-day free trial is also now available for families wishing to put Disney+ to the test without committing to a full subscription. "We humbly hope that this service can bring some much-needed moments of respite for families during these hard times".
More than 600 episodes of The Simpsons will also be available from launch day, alongside various animated classics and live action features.
Audiences can stream Disney+ on almost all major mobile and connected TV devices from today, including gaming consoles, streaming media players, and smart TVs. Specifics of those offers vary per company.
Disney Plus UK pricing is £5.99 per month or £59.99 per year - with the latter shaving 2 months off for the annual commitment.
Carriers with paid-TV services that are also on board so far include Deutsche Telekom, O2 in the UK, Telefonica in Spain, TIM in Italy and Canal+ in France when the country comes online. Disney plans to launch the service in Belgium, Portugal, and the Nordics this Summer as well.
