Colonel Santagura is wearing 2 medals. The 1st is an unaltered U.S. WWII Victory medal. The 2nd is the ribbon from a U.S. Marine Good Conduct medal. The medal itself was altered.
After Neyron hires Barney, he mentions he needs accommodations for his staff (Cinnamon and Willie). Colonel Santagura replies that the house already has servants. Barney insists on working with his own staff, and Neyron agrees. But the other servants are never seen in the house.
The same female extra in an orange dress is seen three different times in the early hotel scenes. In the first, she passes by Phelps towards the front door as he enters and walks through the lobby. In the second after his meeting with Layton, Phelps is walking out of the hotel, and she is seen exiting on his left. In the last while Phelps is speaking with the hotel manager, she is seen approaching the front desk.
At the end, just before General Neyron shoots Layton, Phelps telephones the police from the van to essentially "mop up".
