An interesting thought.
The million dollar ransom in 1909 would equate to about $24 Million today. In 1971, when the movie was made, it would have been worth about $4.5M. That would have been a huge sum back in 1909. In reality, I wonder how long it would have taken to gather that much cash in a far off Texas town?
