Westworld: Evan Rachel Wood strips for Luke Hemsworth

Evan Rachel Wood has bared all in a revealing new scene opposite Luke Hemsworth in the HBO series Westworld.

Luke, who is the older brother of Chris and Liam Hemsworth, examines Evan's robot host character Delores, who sits completely naked in the controversial series.

Westwood is based around a group of android hosts who live in a vast Western theme park where the rich can pay to act out their every fantasy - including rape and murder - until the robots seem to gain consciousness and seek revenge after a coding malfunction.

In another shot Evan's character sits topless with a hand just managing to cover her modesty.

The series, which is based on the futuristic 1973 Michael Crichton movie by the same name, has reportedly cost HBO $100 million and has faced multiple production delays.

Westworld debuted on the network in the US over the weekend, however Evan, who has also starred in True Blood and Mildred Pierce, has defended the show's violent content, urging the critics to "wait for the context".

"It's absolutely very rough. I don't like gratuitous violence against women at all, but I would wait for the context in which it's being used," she recently told Hollywood Reporter.

"As the show progresses, the way it's being used is very much a commentary and a look at our humanity and why we find these things entertaining and why this is an epidemic, and flipping it on its head," she added.

"The roles for the women on this show are going to be very revolutionary. It's very gender-neutral. I would ask, as somebody who is an advocate against any kind of abuse or violence and is outspoken about it, to give it a chance and wait to see where it's going. I think it will surprise people."

Westworld also stars James Mardsen, Ed Harris and Anthony Hopkins.
