You can watch all eight Harry Potter movies through several streaming options:

• Hulu offers all eight Harry Potter movies along with the Fantastic Beasts prequels as part of the Disney+, Hulu, Max bundle starting at $16.99 per month

• Max (formerly HBO Max) currently streams all eight Harry Potter films and the Fantastic Beasts movies in many regions worldwide

• Peacock also streams the complete Harry Potter movie collection, though some versions may have edits or advertisements

• Netflix streams Harry Potter movies in certain regions such as the UK, Ireland, Italy, and Japan

• You can also purchase digital copies from platforms like Amazon Prime Video and Google Play, though quality and versions may vary

For the best experience, physical media like Blu-ray or the Hogwarts Collection DVDs provide uncut versions and bonus features, but they can be expensive and out of print

. In summary, the most reliable streaming access is currently via the Disney+, Hulu, Max bundle or Max alone, with Peacock and Netflix available depending on your location
