Simon

“He loves you. Do what he says.”

In 1980, a think tank of scientists sets out to persuade Simon Mendelssohn (Alan Arkin), a psychology professor, that he is a being from another planet. Marshall Brickman, who wrote and directed, plays the experiment straight, with Madeline Kahn as Dr. Cynthia Mallory and Wallace Shawn among the researchers. The group wants a media circus, and Simon is the test person who has to believe it.
