Currently the only place where you can stream Pina is on The Criterion Channel. There are a few good documentaries on there (like Heart of a Dog) so definitely check it out. Pina is not currently available through Netflix or Prime Video but we will update this page if we find it on there in the future.
If you don't have access to The Criterion Channel then you can still buy or rent Pina to watch online from a few other platforms, including YouTube, iTunes and Google Play Movies. This will only cost you $2.99
