Aaron Paul teases a bigger story for Westworld season 4. Following his breakout role as Jesse Pinkman on Breaking Bad and that show's eventual finale in 2013, Paul joined the cast of HBO's cerebral sci-fi series in its third season as Caleb Nichols, a former soldier-turned-petty criminal. Nichols takes jobs through the RICO app, secretly run by rogue quantum computer Rehoboam, and became a central character in season 3 (which takes place almost entirely outside the series' titular park).

Westworld is inspired by the 1973 film of the same name written and directed by Jurassic Park author Michael Crichton, HBO's loose adaptation is created by Jonathan Nolan and Lisa Joy. Season 1's story begins inside the Wild-West-themed amusement park populated by highly advanced humanoid robots known as hosts. Seasons 2 and 3 expand further and further outside the park as the hosts gain sentience and become integrated into a dystopian society dominated by an omniscient supercomputer known as Rehoboam, which Dolores (Evan Rachel Wood) sacrifices herself to destroy. Audiences also saw the Charlotte Hale clone gearing up for a war against humanity, with whom Caleb will come face-to-face in season 4.

In a new THR interview discussing his new movie Dual and upcoming appearance in Better Call Saul, Paul also teased what's to come in Westworld season 4. Recognizing how Nolan and Joy tend to go "bigger as the seasons go on," the actor teased a more substantial story for the upcoming season. Read what he shared below:

I can’t wait for people to see what this season is all about. They always go so much bigger as the seasons go on. Yeah, they definitely put me through it. That is certain. But it was done in a beautiful way, and I loved doing it.

HBO has been noticeably hushed about Westworld season 4, which started production last June and wrapped in December, realizing some brief footage in a sizzle reel shortly after. Instead, most of the information about the upcoming season has come from the casts' interviews for other projects. Paul's recent tease aligns with what Joy has said about season 4, revealing that the show will expand to new worlds. The original film featured a Roman World and a Medieval World which writers could introduce in the upcoming season.

Westworld Season 4 still does not have a release date, though past trends suggest it will debut sometime this year, likely in the summer. Other than the delays incurred by the COVID-19 pandemic, perhaps season 4 is taking longer than expected due to its increased scale. Westworld has managed to reinvent itself with each season, which isn't likely to change this time around.
