None. The cast is mostly male, being that this film takes place at a military base during the Second World War.
There are a couple of pin-up women shown.
Violence & Gore
Mild
While this is a "war movie", there is actually very little violence. Most of the battles are only "talked about" and not actually seen. The few scenes of planes actually in battle consist mostly of stock footage from actual planes in combat. This footage is black and white and not in the best of shape, so even it is fairly tame.
Profanity
None
Mild cursing and insults. No overly profane language to speak of.
Alcohol, Drugs & Smoking
Mild
Drugs, recreational: None
Many characters smoke and drink socially. Several times men are shown to be very drunk.
Frightening & Intense Scenes
None
Characters do go into aerial battles while death is very much a possibility, however most of the violence and suspense is implied and happens "off camera."
