Forging the weapons of war, official United States war film" poster
The pattern
This still is filed under Us-versus-them positioning.
Define
The buyer is invited into a side. The product is what we use. The named other is what we refuse.
Mechanism
Identity contrast. Choosing the offer is choosing a group. The out-group does as much work as the claim.
Verdict
The category is crowded
Why it works
Relies on official government authority and the intrigue of getting a behind-the-scenes look at industrial scale to drive theater attendance.
Steal this when
You are promoting a documentary or behind-the-scenes look and want to emphasize its official, authoritative nature.
