Watch the trailer for Westworld - it could be bigger than Game of Thrones

Westworld

is a new HBO series coming out in October this year and it's looking like it will draw the crowds.

It's based on the 1973 sci-fi Western thriller film with the same name. It is about a highly realistic theme park where robots are acting as people.

It's been described on IMDb as "a dark odyssey about the dawn of artificial consciousness and the future of sin."

Sound morbid enough for you?

It stars Sir Anthony Hopkins as well as Ed Harris, James Marsden and Thandie Newton.

YouTube subscribers commented below the trailer saying how excited they are for the release.

"This has me very intrigued. And what a cast!" says Leigh Douglas

Jd899 says "not too long now. It looks amazing can't wait."

Some people are even saying the storyline might be better than Game of Thrones.

Who knows? Time will tell.
