After four seasons, HBO has canceled "Westworld," the network announced Friday.

The news of the sci-fi drama ending comes as a shock to fans, considering the Season 4 finale aired on Aug. 14.

"Over the past four seasons, Lisa and Jonah have taken viewers on a mind-bending odyssey, raising the bar at every step. We are tremendously grateful to them, along with their immensely talented cast, producers and crew, and all of our partners at Kilter Films, Bad Robot and Warner Bros. Television. It’s been a thrill to join them on this journey," HBO confirmed with Fox News Digital in a statement.

"Westworld" was created by Lisa Joy and her husband Jonathan Nolan and executive produced by J.J. Abrams. The husband-and-wife duo shared their sentiments toward the show ending on social media through a series of posts.
