The series is loosely based on Michael Crichton's 1973 feature film Westworld, which is set in a futuristic theme park where visitors can make their fantasies a reality, with the help of android robots. Miranda Otto will play Virigina Pittman, the head of the park's Quality Assurance department.
Here's a brief description of the character from Entertainment Weekly.
"Her brutal honesty with her colleagues and her ruthless efficiency in dealing with malfunctioning 'property' have made her a formidable and unpredictable power player in Westworld."
She joins a cast that includes Anthony Hopkins, Evan Rachel Wood, Jeffrey Wright, Rodrigo Santoro, Shannon Woodward, Simon Quarterman, Angela Sarafyan, Ingrid Bolsø Berdal and James Marsden.
J.J. Abrams is executive producing the pilot, which was written by Jonathan Nolan (Person of Interest) and Lisa Joy (Burn Notice), through his Bad Robot production company, alongside Jerry Weintraub and Bryan Burk. Production on the pilot is slated to begin later this month.
On the small screen, Miranda Otto most recently starred in the short-lived Fox sitcom Rake. She has also starred in features such as I, Frankenstein and the upcoming Western The Homesman.
