Westworld is back with its fourth season and it's fair to say things have changed quite a bit since we were first introduced to it back in season 1.

With the central action leaving the parks behind after season 2, season 3 focussed on the AI 'hosts' infiltrating the real world, transporting the action to a Blade Runner-esque futuristic city.

There have been a fair few changes within the cast too, with Dolores (seemingly) perishing at the end of season 3 and Aaron Paul's new season 3 character Caleb becoming a crucial part of the ensemble.

But what can we expect going into season 4? Which cast members and characters will be back, and who's joining the show fresh for the new episodes?

Read on for everything you need to know about the cast of Westworld season 4.
