Westworld is loosely based on the 1973 film by the same name starring Yul Brenner.
Why would you say "Loosely" ?? it's just the same but Updated
For you young guys out there ... West World the Movie was Far Far ahead of it's time. Now jump ahead 40+ years later ... and I'm not a fan of taking an old Movie or TV show and re-booting it. But this show is pretty Good.
and it's only the first one thus far.
If they stay on course .... I think this is going to be a Great show.
just my 2 cents
