- The action movie hero is the Brand
- The stuntman who makes him look good is the commodity
The hero cannot be replaced (or there are very few choices) so he commands a king's ransom for his performance.
The stuntman is unknown to the public and therefore replaceable and so makes a lot less for a much more dangerous and difficult job.
I Watched the Quantum of Solace over the weekend which triggered this train of thought. Great movie BTW.
PS: No offense intended to any stuntmen - just making a point.
