When Project Hail Mary Will Stream on Prime Video

Project Hail Mary hit theaters today and has drawn strong early reviews, currently sitting at 95% on Rotten Tomatoes with some calling it the highest-rated Ryan Gosling movie yet. The film follows Ryland Grace, a schoolteacher who wakes up alone on an interstellar spacecraft with no memory and must solve the mystery of a substance threatening the sun; along the way he befriends an alien he names Rocky.

The movie will eventually appear on both Prime Video and the MGM+ app, but the timing can vary. Recent MGM releases show different windows: Blink Twice reached MGM+ about 89 days after its theatrical debut and only later arrived on Prime Video, while Melania reached Prime Video in under 40 days.

Given Project Hail Mary’s strong reception and box office prospects, it is expected to follow a longer theatrical window. Based on that pattern, Project Hail Mary is likely to hit MGM+ around Friday, June 19, 2026 — roughly 90 days after release — and could arrive on Prime Video the same day or a month or two later.
