Off top of head, in genres specified: probably

The Incredible Shrinking Man or Bride Of Frankenstein

The Magnificent Seven or Stagecoach or Westward The Women or Drums Along The Mohawk or Shane

The Bridge On The River Kwai or The Real Glory or The Red Badge Of Courage or An Incident At Owl Creek Bridge

But I don't set up to be any sort of authority on film, these are just personal choices, as you ask. And I'd probably recall a completely different set if asked again in 6 months time!
