US TV network HBO has released the first full-length trailer for 'Westworld' series two.
The trailer aired during Sunday night's Super Bowl. It was the first time HBO has aired a trailer for a specific series during the wildly popular sporting event.
The trailer doesn't give too much away. But we presume the second series carries on where the first left off. Only this time there are mechanical bulls to contend with.
'Westworld' is based on the Michael Crichton film of the same name from the 1970s. It's set in the near future, where wealthy business people can escape into a fantasy Wild West-style world populated by robots acting as cowboys. These robots aren't supposed to be able to harm humans. But as ever, things go wrong and the robots run amok.
Series two starts in April on HBO. In the UK, it airs on Sky Atlantic.
