Nit-pick of the day: Sellers' Chauncy Gardener became the advisor to the president, not the president.
Also, the movie was based on a 1971 Kosinski book. So any metaphor
for Reagan was not only a Hollywood conceit, but to the extent it
existed at all, their own creation.
And the theme of Kosinski book was lifted from a famous earlier Polish novel.
By the way, I believe that Peter Sellers, himself, was rather conservative politically.
Does anyone have any information on this?
