Perseverance pays off. Gender doesn't dictate intelligence or competency (the 1940s, specifically the Bletchley Project in England, helped usher in gender equality in the sciences). Empathy is a major theme.
Positive Role Models & Representations
Bullies torment a classmate at a boys' school; they trap him under floorboards, tease him in the yard, and shove him around. Scenes of battle during World War II show bombs being dropped, buildings exploding, and soldiers firing at enemies. Professional arguments at work are laced with personal vendettas and implied threats.
Couples flirt in social situations. Sexual identity is a theme of the movie.
Some swearing; mostly British slang from the period. One character is labeled a "toff" and a "poof."
Ease of Play
Social drinking and period-accurate smoking. A character makes a reference to taking drugs that cause chemical castration.
