I've seen the West End play, read the play transcript, and read the novel too. This (in my humble opinion) is a magnificent adaption of this very powerful play based upon R C Sherriff's real-life experiences in the trenches of World War One. It captures the tragedy of war, courage in the face of hopelessness, friendship, and regret among a host of human emotions. The acting is superb, the sets and attention to detail like nothing I remember seeing in a film set in World War One. I cannot recommend it enough. How sad that it has had such a limited cinema release on the Centenary of the year in which the film is set. Almost as if these men are all forgotten now? Not by me.
