The scene where Fish reads the book to his blinded fellow astronaut. In a film trying too hard to have huge meaningful moments, the quiet humanity of this one really stood out.
President Beck's final speech at the end of the film. Also counts as a Rousing Speech:
President Beck:We watched as the bombs shattered the second comet into a million pieces of ice and rock that burned harmlessly in our atmosphere and lit up the sky for an hour. Still, we were left with the devastation of the first. The waters reached as far inland as the Ohio and Tennessee Valleys. It washed away farms and towns, forests and skyscrapers. But, the water receded. The wave hit Europe and Africa too. Millions were lost, and countless more left homeless. But the waters receded. Cities fall, but they are rebuilt. And heroes die, but they are remembered. We honor them with every brick we lay, with every field we sow, with every child we comfort, and then teach to rejoice in what we have been re-given. Our planet. Our home. So now...let us begin.
