1. The Incredible Shrinking Man (1957) Film
This classic story was adapted by Matheson from his own 1956 novel, The Shrinking Man. The film stars Grant Williams as Scott Carey, a man who begins to shrink after exposure to a mist from a strange cloud while vacationing with his wife. After a few months, Scott begins to notice that his clothes are not fitting him. Alarmed by the changes he consulates a physician who tells him that he is perfectly healthy. Soon after, Scott's height and weight are rapidly decreasing and eventually winds up 3 feet tall. He is given an antidote that will stop his shrinking but will not be able to return him to normal size. The antidote seems to work for a while until he notices that he is getting even smaller and resorts to living inside a dollhouse. Scott learns that he must cope with his life as a miniature man while trying to survive against his own cat and a house spider. The film was directed by notable science fiction director Jack Arnold and was hailed by critics for its story and visual effects. Matheson soon wrote a treatment to a sequel titled, The Fantastic Shrinking Girl, but it was never produced. In 1981 a comedy remake of the film was made called The Incredible Shrinking Woman, starring Lily Tomlin. The Incredible Shrinking Man was added to the National Registry by the National Film Preservation Board in 2009. To this day it remains as a science fiction classic and is best film adaption of of Richard Matheson's work.
