Casablanca
A beloved WWII-era romantic drama rated PG, with mild gun violence, pervasive drinking and smoking, and a subtle implication of coerced sex. Content is restrained by any standard but the wartime themes and slow pacing may engage older viewers more than younger ones.
If you’d rather skip
French police round up civilians and refugees; a man makes a run for it and is shot with a gun, falling to the ground. A second character is captured and dies later off screen. Guns are shown and fired.
A character named Ugarte is arrested; it is strongly implied he is later executed off screen by German authorities without trial.
A married woman obliquely tells the male lead that she must exchange sexual favors with a corrupt official for travel documents; the exchange is verbal only and handled with period-era restraint.
