Fans gaped in amazement while media photographers snapped away frantically.
At the front end of the red carpet, Martin, Leonardo, and Nicholson led a docile old cow towards the theatre.
Nicholson, wearing sunglasses, couldn't stop grinning as he walked the cow down the red carpet; gifting it to his old buddy director was a first for him, and he found it especially amusing.
Leonardo glanced at Martin and thought to himself that only a bastard could come up with such a novel stunt.
Martin, leading the way, walked the cow to the middle of the red carpet and waved to the crowd.
The surrounding fans let out ear-piercing screams.
Photographers with access to both sides of the red carpet snapped away like mad, constantly pressing their camera shutters.
Leonardo said, "We're going to snag the front page of the North American entertainment section."
