HBO has teased a new trailer for its big-budget drama Westworld — and it would appear the robots are not going down without a fight.

In the clip, we can see Dolores on horseback, pointing a shotgun at some unfortunate few, while William seems slightly confused as he surveys a tiger cadaver. Best of all, there's a return of Ed Harris’ Man in Black character, who directs an ominous smirk at the camera just before the footage ends.

The teaser, debuted at San Diego Comic-Con, certainly whets the appetite, but don't go getting too excited just yet: the show isn't slated to return until some time in 2018.

Watch above, and then check out the recently debuted trailer for Justice League.
