HBO’s ambitious Western sci-fi mash-up Westworld had some serious star power behind it. The series was co-produced by JJ Abrams, and its star-studded cast included Ed Harris, Anthony Hopkins, Evan Rachel Wood, and James Marsden.
The show's fourth season, which aired in 2022, reportedly cost $160 million to create. That works out at a whopping $20 million per episode, or $21.7 million (£16.8m) today.
While praised for its mind-bending CGI, the staggering production costs were ultimately the show's downfall. Plans for a fifth and final season were axed, much to the shock of fans.
