If you don't mind, I'll take a stab at moving the articles in the category used for the 70s films to a new name. "Westworld (Film)" sounds almost the same as the article for the '73 film itself (the only difference is a capitalised/non-capitalised "f" in the brackets). I've named the new category for the two films "Westworld Film series (1970s)". Hopefully it should help prevent confusion in the future. It was getting iffy having the Futureworld articles under the same category as those related to the '73 film, while the name seemed to indicate it's only about the '73 film.
