Anthony Hopkins is the Oscar-winning eminence behind such prestige films as "The Remains of the Day" and "Silence of the Lambs." But he came to TV as Robert Ford, the ominous creator of the creepy amusement park in HBO's "Westworld."
Paul Giamatti specializes in twitchy, over-the-top characters in films such as "Sideways" and "Cinderella Man." On Showtime's "Billions," he played a driven U.S. attorney battling white-collar criminals.
You've seen Isabella Rossellini in movies like "Blue Velvet" and "Joy," but in 2016 she turned up as a main cast member in the Hulu drama "Shut Eye."
And finally, another "Westworld"-er: British actress Thandie Newton, well-known for such films as "Mission: Impossible II" and "Crash," stars as Maeve Millay, the madam of the amusement park in the sci-fi series.
