Four Oscars went to this dramatization of the life of Nobel Prize winner John Nash.

Ron Howard directed this 2001 film, which also stars Jennifer Connelly, Ed Harris and Christopher Plummer.

Narrated by Richard Chamberlain, this program uses reenactments to tell the story of the mysterious kingdom unknown by the western world for more than two centuries.
