The film’s from the 50s/60s and features a family who are either feuding with another family or have angered someone. Gradually, members of the family keep being killed off including one man, I think one of the sons, by a well in the front of the house. It’s a period film, either a western or a similar time period and I think the film was in colour. Any help would be appreciated
Just a guess, maybe
“The Big Country” (1958)?
“Feuding families vie for water rights in the old West.”
