Fortunes Of War

Fortunes Of War is a 1987 adaptation of the Olivia Manning series of novels produced by the BBC with funding provided by WGBH for PBS Masterpiece Theatre. This one had an impressive cast including Kenneth Branagh and Emma Thompson as the featured couple of the story. They must have hit it off pretty well off-camera as they ended up being married for a period after this.
