Notably, nobody can ever forget the way he gets his team moving in the morning. “Alright, sweethearts, what are you waiting for? Breakfast in bed?” Apone would ask them. Humorously, when one soldier complains about his feet being cold, the sergeant responds, “What do you want me to do, fetch your slippers for you?” Certainly, Matthews' portrayal of Apone is one of the film’s most entertaining aspects.
