Movies like Tolérance (1989)

An English hermit has somehow been brought to France in the period following the French Revolution, and prior to the Napoleonic Era, a period (1795-1799) known as "The Directory." He eventually comes down out of his tree into a chateau owned by an Italian nobleman and his wife. Before long, the hermit has washed and bathed and become quite presentable, even charming. However, his appearance in their midst is like a sentence of death for many of those who associate with him.
