Simon

This bizarre comedy centers on Simon Mendelssohn (Alan Arkin), a preening professor of psychology who is mischievously duped into believing that he is an extraterrestrial. Dr. Carl Becker (Austin Pendleton) and the other idle think-tank members responsible for his condition also manage to convince the public that he's an alien, resulting in misadventures involving armed soldiers and eccentric commune dwellers when Simon escapes from the halls of academia and out into society.
