Not much else is known beyond this bit of casting, something that shouldn't come as a surprise to Westworld fans. Creators Jonathan Nolan and Lisa Joy like to maintain the highest level of secrecy possible, so that not even the cast gets the whole picture.
If we had to wager a guess, however, we'd say that Paul could portray a young and ruthless tech billionaire that wants to buy Westworld out from Delos, stopping at nothing to prove that William (aka the Man in Black, played by Ed Harris) is no longer fit to run the park. Again, that's just a guess and we could be wayyy off, but that would be cool to see, wouldn't it?
Paul reprises his role of Todd Chavez in Season 5 of BoJack Horseman, which drops on Netflix tomorrow. He has also joined the Apple anthology series, Are You Sleeping?, which co-stars Lizzy Caplan and Ron Cephas Jones, and explores a family's journey to uncover the mystery surrounding their late father's death.
When he does make his Westworld debut, Paul will be the second Breaking Bad alum to appear on the sci-fi series after Giancarlo Esposito (Gus Fring), who made a small, but memorable cameo in the second season.
