‘Project Hail Mary’ Sets Streaming Date on MGM+

Amazon MGM Studios‘ Project Hail Mary will be available to stream on June 18, repping a 91-day theatrical window. For all the cynicism over Amazon crushing the theatrical window with movies like Saltburn and Red One in the past, well they’re clearly not doing any damage here on what is currently the third-highest grossing movie of 2026 with more than $678M worldwide.

But get this — the Lord and Miller directed and produced, Ryan Gosling starring feature take of the Andrew Weir novel won’t be available to stream exclusively on Prime Video, rather sister service MGM+.

Why is that? We’re told it’s a horses for courses business decision at the streaming and theatrical studio. Different movies in the Amazon MGM verse go through different models, i.e. Project Hail Mary went through full windows including PVOD with MGM+ being the pay-one. The Oscar-winning American Fiction was another title that went through full windows with a pay one on MGM+.

Those movies that go from theatrical to Prime Video, are greenlit differently, often have their budgets covered by Prime and are monetized under a different model internally.
