Several years ago, perhaps 45 or 50, there was a movie about a Scot in a British Army hospital. He was disliked, but in some manner touched everyone. He died and soldiers who disliked him were sad. I barely remember any more. It seems the Scot soldier was played by an up and coming british actor.

Sounds like The Hasty Heart (1949) (http://uk.imdb.com/title/tt0041445/)
