Warning: If youve yet to watch the currently available episodes of Westworld, there might be spoilers ahead.

One of the standout performances from HBOs young sci-fi series Westworld thus far is that of Evan Rachel Wood, who plays Dolores.

What fans of the show might not know is that when writing Woods character, the Westworld team was inspired by an iconic painting. In an interview with Entertainment Weekly, showrunner Jonathan Nolan reveals that Andrew Wyeths 1948 painting was used as a jumping-off point of sorts for Dolores, a cyborg who plays a ranchers daughter in the Wild Westthemed park on the show. Over the episodes, we see her gain some sort of perception beyond her programmed narrative.

It was a tilt of the head toward all the different stories that inspired us; a classic protagonist whos on a heros journey with a darker twist to it, said Nolan, also referencing Alice in Wonderland as an inspiration. She starts in what should be the happy homestead but its not and she goes out looking ultimately for herself.
