March of the Penguins (2005)
Can you ever see a penguin again without hearing Morgan Freeman's luscious voice in your head? But beyond its dulcet-toned talent, Luc Jacquet's innovative story of survival in the wild elevated its shuffling subjects beyond their own adorableness. They weren't just penguins. They were survivors. They were pragmatists. They were us just marching on in the face of the constant obstacles of an inhospitable world.
