“Regretting You” already finished its main theatrical run in late 2025, and by early 2026 it is no longer in wide release in most countries. It moved to streaming (Paramount+) in December 2025, which usually happens once the main theater window is essentially over.

Quick Scoop

  • The movie opened in U.S. theaters on October 24, 2025.
  • It premiered on Paramount+ streaming on December 23, 2025.
  • By the time a film hits a major streaming service, wide theatrical runs are typically winding down or done, with only occasional holdover or special-event screenings.

So if you are wondering “how long will ‘Regretting You’ be in theaters?” in January 2026, the practical answer is:

  • The standard wide theatrical window already passed (roughly October–December 2025).
  • You might still find:
    • Limited or discount-theater showings in some locations.
    • One-off special screenings or events.

But for most viewers, the reliable way to watch it now is via Paramount+ , not regular cinemas.
