Westworld, the heir apparent to Game of Thrones in terms of buzz, is coming back sooner than expected. A press release overview of scheduling for all HBO programming lists Westworld season 2 as premiering in spring 2018, with a more precise release date likely to follow soon (along with a Sky Atlantic one for UK viewers). The second season is filming right now, with a first trailer for it being unveiled at Comic-Con last week.
It didn't have a huge amount of new footage to show off but was still quite revealing, seeing Bernard standing over a dead tiger, Maeve exploring Westworld's control room - bodies everywhere, and the Man in Black covered in blood.
