Film opening - Mise-en-scène

As we're making the opening for a historical film set approximately 80 years ago, Mise-en-scène is incredibly important for making our opening look believable, interesting and showing good continuation.
We wrote a list of items we could potentially need and went about trying to collect them. This ensured that when it came to filming we had a convincing set with excellent Mise-en-scène.

• Any bullets, bullet casings or shells.
• Any military style uniform, such as boots, military jackets and hats.
• Indicators of the location, era and situation the characters are in (war time) 
•  Documents and papers, some with black boxes over parts of the text.
• Ashtray
• A smoking fire/camp fire, or a campfire effect.
• Any replica weapons

Combined with our plans of making the titles and music represent the location and era, this will make our film opening look authentic.
