"Westworld" Season 3 will begin soon. With the release of the complete trailer, we can see how the series will pique our interest and what role the hot new cast member (Aaron Paul) will play.

While the first season of the series featured the titular amusement park, the second season introduced several new amusement parks, including Shogun World, themed on feudal Japan. Season 3 will also depict the real world outside of the amusement parks.

Will Westworld Season 3 get us hooked again? Here's what we know so far.

The Westworld Season 3 premiere can be seen on HBO on March 15, 2020 at 9pm ET. The eight-episode season will air one episode at that time on Sundays.

The first official trailer for "Westworld" Season 3 recently arrived. In this trailer, a civil war erupts among the AIs, with some still loyal to their masters and others trying to turn on humanity. There's also plenty of action:

HBO released the first trailer for "Westworld" Season 3 at San Diego Comic-Con (SDCC) 2020, where Dolores (Evan Rachel Wood) surprised fans with footage of her walking around the real world outside Westworld's walls. You and I have no mothers or fathers," she says, "and we talk about outwitting our masters.

Other familiar faces include Maeve (Thandie Newton) in the World War II world and Bernard looking through the archives of a retired robot at Delos.

Aaron Paul appears in the trailer as a new character, Caleb, hanging from a building in one scene. We know about this character from the teaser unveiled in the previous season of "Game of Thrones," and he appears to be a criminal struggling to survive.

A robot is gunned down and Charlotte Hale (Tessa Thompson) taunts another robot. Everything is chaotic.

HBO revealed that Westworld 3 has received a release date in a trailer centered around the concept of Divergence. The clip presents a timeline highlighting the Hong Kong protests and the impeachment of Donald J. Trump, aka the 45th President of the United States. It then presents events in our future, beginning with the ecological collapse in Indonesia in May 2020.

This timeline appears to trace the decline of humanity present in the Westworld story. And April 17, 2039 is presented as the date when "Solomon" build 0.06, Westworld's underlying AI, was "system activated" in an undisclosed location.

It ends in February 2058, with an off-screen voice saying, "Something has not been explained, we." At least that's one take. This "you," fans believe, is Dolores, the protagonist of Westworld's first season.

Season 3 of Westworld seems to test the limits of free will, or at least what happens when there is no free will. We got a little taste of this possibility at CES 2020, where HBO invited us to an "Incite-sponsored" dinner where all our order decisions were made.

HBO even released a trailer for this Incite organization, which presumably plays a role in the struggle that Caleb (Aaron Paul) is enduring.

If this message is too subtle for you, check out this animated "Westworld" Season 3 poster:

The new cast includes the aforementioned Aaron Paul, who plays Caleb. The cast is rounded out by two other major new signings: Lena Waithe ("The Chi," "Master of None") and Vincent Cassel ("Ocean's 12," "Black Swan"). Also on board will be veteran HBO actor Kid Cudi ("How to Make It in America").

The returning cast includes:

The trailer above shows that Bernard is very afraid of Dolores and is trying to find a solution to her possible domination. Whose side will humanity take in this war? Will Caleb represent them?

A more far-fetched theory is the rumor that this real world Dolores is exploring is not so real after all. Yes, the Season 2 finale suggested that Dolores is breaking the seal between the familiar park and "our" world, but what if that is not the case?

Why not, ScreenRant notes that the theme for Season 3 is "New Worlds" and that each park is called a world (Westworld, Shogun World, and Warworld, inspired by WWII-era Italy).
