Bad Russians

A large, monstrous creature with pale, wrinkled skin and a wide mouth roars aggressively, its face filling the frame as it moves forward. The scene cuts to a wide shot of a massive army of similar creatures marching across a desolate landscape toward a distant, fortified city under a dark, cloudy sky. The sequence loops, showing the creature's intense expression, the army's advance, a small object falling from the sky, and the creature's face again in close-up.
