Meet the cast of Westworld

Set in a 'theme park' based on the Wild West, hyper-realistic androids help rich clients – or “Newcomers” – live out their fantasies in a risk-free environment with no consequences. That is, until the android “Hosts” start behaving erratically…

Here’s everything you need to know about the key characters, and who plays them, ahead of the series debut tonight at 9pm on Sky Atlantic.

Sir Anthony Hopkins – Dr Robert Ford

Who does he play?

The creative director of Westworld, Dr Robert Ford is seemingly cut from the same cloth as Jurassic Park boss John Hammond (Richard Attenborough) – perhaps not a coincidence, as both the dinosaur movie and the original 1973 Westworld film were written by Michael Crichton. Like Hammond messing with ancient genetics, Dr Ford has started to re-program his androids to dream and access old memories.

Better known for his big-screen roles, the 78-year-old acting heavyweight memorably starred as cannibalistic serial killer Hannibal Lecter in the movie The Silence of the Lambs.

Dolores is a belle of the American West who discovers that her entire life is not everything it seems.

The gunslinger’s identity and motivations are shrouded in mystery, but the Man in Black – playing a similar character to Yul Brynner’s mysterious Host in the original movie - is a visitor to Westworld who may or may not be human.
