Although Ealing Studios are best known for their comedies, they did make quite a lot of serious films. Besides the two I mentioned earlier they made various war films such as "Went the Day Well", the extraordinary film made in 1942 about an English village being invaded by Germans, ultra serious and scarily believable. Then "It Always Rains on Sunday" (1947) which is a foreunner of kitchen sink dramas which started about 10 years later. "Scott of the Antarctic" (1948). "The Blue Lamp" (1950). Some other later films, the last of note being "Dunkirk" (1958). The studio ceased for many years but did start again though I don't think anything as good as those films.
