There is an episode of 'Death Valley Days' with Ronald Reagan playing the part of Poston. The plot from wiki says:
"In the story line, Poston is a mining developer and surveyor engaged in a race against time to reach San Diego, California, for an important meeting with bankers."

Although wiki doesn't specify who the bankers were, the episode was on just the other day, and the 'bankers' were named as Rothschild.
