Will The Super Mario Galaxy Movie be on Peacock?

As of May 30, 2026, there is no officially announced film titled "The Super Mario Galaxy Movie." A sequel to The Super Mario Bros. Movie was scheduled for theatrical release on April 3, 2026, but the specific title you asked about has not been confirmed.

If a future Mario movie is released by Universal/Illumination, it would be expected to follow Universal’s usual streaming pattern, which typically brings theatrical films to Peacock first during the pay-1 window. That means the answer would be: likely on Peacock eventually, but not confirmed unless Universal or Peacock announces it.

Because release schedules and licensing windows can change, the safest move is to check the official Universal and Peacock announcements closer to the home-release window.
