Jurassic Worlddirector Colin Trevorrow unleashedhis secret short filmon FX Sunday night and released it online soon after.

In just eight-and-a-half minutes, America in a post-Jurassic World: Fallen Kingdomis already one terrifying place.

Battle at Big Rock takes place one year after the events ofFallen Kingdomat Big Rock National Park.

That film ended with life finding a way once again and the dinos fleeing into the open world.

The answer comes in Battle at Big Rock, where a familys camping trip turns into a survivalist nightmare.

Trevorrow wrote Battle at Big Rock withJurassic World 3screenwriter Emily Carmichael.

We really wanted this technology, this genetic power, to go open-source at the end of the film.

The open-sourcing of any technology, like nuclear power, thats the scary side for me.

Clearly, humans are no longer at the top of the food chain.
