This is an early work of Terence Young, the director, but a well-made, engrossing and ultimately very moving British war drama of World War II. Interestingly a very young Desmond Llewelyn has a cameo role as a Welsh tank commander, and when it came time for Young to find a new Q for the second James Bond movie, the original no longer being available, he remembered Llewelyn and cast him in what is now the longest running continuous role in the James Bond saga.
