The cover does not disclose which movies are in this "World War Collection, so let me solve that mystery.
Disc 1. The Sound Barrier. This film has nothing to do with a world war and nothing to do with the real story of beaking the sound barrier. It is not a bad flick, but I cannot get my head around having some fictional Brit be the first man to fly faster than sound. Forget this nonsense and watch The Right Stuff to see a real hero, Chuck Yeager.
Disc 2 has two films. King and Country. A WW1 story that tells the story of a court martial. It covers the same ground as the much supiror Paths of Glory, but it is still worthwhile in its own right.
Angel One Five. A sturdy and unremarkable story of a fighter squadron in the Battle of Britain.
Disc 3. The Captive Heart. A real gem about the lives and long-distance loves of British POWs in WW2.
