HBO was forced to suspend production for “Westworld” Season 2 because of a medical emergency. HBO

Is the release date of “Westworld” Season 2 in danger of being pushed back? There’s a chance it might be since HBO halted production after an actor in a recurring role sustained injuries off-set.

HBO did not reveal who the actor was, or what the injury was about. The other production unit’s work was thankfully not affected.

“Due to a medical emergency involving a performer in a recurring role on season 2 of Westworld, filming on one of the two units has been temporarily suspended,” HBO said in a statement to Deadline. “The cast member was not on set when this occurred, and out of respect for the performer’s privacy, we have no additional details to share, other than that everyone at Westworld sincerely hopes for a quick recovery.”

The production schedule for Season 2 has been pretty “insane,” according to Ed Harris, who plays the Man in Black. He said that they are in better shape compared to when they were filming Season 1, but it appears show creators Jonathan Nolan and Lisa Joy are keen to get things done quickly since there are several groups filming at different locations on any given day.

“So far, we’ve shot some from episode 1, episode 2, some from episode 4, some from episode 10. They’re committed to having the scripts done to shoot so we’re done by Christmas,” Harris told Collider. “I’m glad that I am not a person who’s trying to schedule the days of filming on this thing, because it’s insane. Sometimes you’ll have two, three different episodes being shot. Different crews, different locations; I don’t know how they get it all done.”

But one thing’s for sure - the show will continue to provide fans with a lot of jaw-dropping moments. Harris’ co-star Evan Rachel Wood, who plays host Dolores Abernathy, she told Entertainment Tonight that next season is actually “twice as ambitious as the first season.”

The first season was already filled with shocking twists and turns, but the second season lived up to her expectations. “I didn't think the show could shock me and it continues to do so,” she explained. “It’s going to be everything and more.”

“Westworld” Season 2 premieres on HBO in 2018.
