HBO revealed the second season trailer for sci-fi thriller Westworld at the show’s Comic-Con panel on Saturday. The violent and action-packed video — set to Sammy Davis Jr,’s “I Gotta Be Me’ — showed the robot uprising in futuristic theme park, the return of the Man in Black (Ed Harris), and Dolores (Evan Rachel Wood) gunning down fleeing guests while on horseback, among other scenes.

Showrunner Jonathan Nolan said at the show’s Comic-Con panel:

“My perception of reality has shifted significantly since I started doing this. I’m convinced we must be in a simulation of some kind. I just did a tequila shot with Ed Harris in a parking garage at Comic-Con.”

Westworld will return in 2018.
