Die My Love is a recent film that has been released in theaters and is rolling out to streaming platforms. Based on current reporting, it is not currently available on major streaming services, but will eventually be accessible for on-demand rental/purchase and streaming on the platform that acquired distribution rights. Direct answer:

• At the moment, you won’t find Die My Love on Netflix, Prime Video, Disney+, or similar mainstream services. It’s primarily a Cannes-era release that has been picked up by a specialty streamer.
• The film is expected to arrive on demand (buy/rent) soon after its theatrical window, and, in the near term, on the platform that acquired distribution rights (not Netflix or the big three services).
• If you’re flexible on timing, the best approach is to check on-demand stores (like Apple TV, Google Play, Vudu, etc.) for rental or purchase options, and monitor the specialty streamer’s catalog for a formal streaming date.
