Westworld, based on Michael Crichton’s 1973 film, has received a full series order from HBO.

HBO Orders Westworld

HBO announced that it was moving forward with Westworld on Twitter Monday, making fans guess the news by providing a clue.

Anthony Hopkins, James Marsden, Ed Harris and Miranda Otto are also starring in the HBO series. The main actors involved in the film have signed multiyear deals.

Jonathan Nolan and Lisa Joy adapted Westworld for the small screen from Crichton’s film. Nolan, Joy, J.J. Abrams, Bryan Burk and Jerry Weintraub are also executive producing.

The show, like the movie, takes place in an adult amusement part run by robots that look uncannily like humans. If killed, the androids have the capability of regenerating, though they’ll have a new persona. The conceit will enable the actors playing the robots to play a number of different “characters” within the role, particularly if the series gets more seasons.

“This is built as a series and, in terms of storytelling, I think the rules are definitely being broken,” HBO programming president Michael Lombardo told The Hollywood Reporter. “The promise of the show, in terms of where it’s going, is exciting to actors, and they want to be a part of this.”

Westworld is joining HBO’s list of impressive dramas that includes Game of Thrones, The Leftovers, True Detective and Utopia, as well as Boardwalk Empire and The Newsroom, which are in their last season.
