I remember watching this movie, the movie opens with a scene with a guy with mental illness who keeps repeating a number, meanwhile something is about to hit earth and his brother is working with a team to prevent it.

The twist at the end is that they hit the asteroid (or whatever is about to hit earth) with something to stop it, then the opening scene is shown again, but this time he adds one to the number indicating that they are caught in a time loop where they keep hitting the asteroid and the time repeats.

It’s a really good plot twist but I can’t seem to find the name of the movie.
