Although it's currently and exclusively only showing in theaters, the first trailer for Christopher Nolan's epic, 'The Odyssey,' leaked online.

The spectacular trailer for Nolan's $250 million gamble is debuting exclusively in theaters in front of Universal's 'Jurassic World Rebirth,' but promptly popped up online.

The teaser, which is 70 seconds long, briefly shows Matt Damon’s lead character Odysseus, his son Telemachus (played by Tom Holland) and a mystery character played by Jon Bernthal. It begins with some narration by what sounds like Robert Pattinson, who plays an unknown character.
