The Incredible Shrinking Man (1957)
Matheson’s breakthrough in the industry was this adaptation of his own novel, The Shrinking Man - the producers later added the “incredible” to the title (“My feeling is, it’s already pretty incredible that a guy is shrinking. Why add the adjective?”, remarked the author). Matheson penned the script himself after forcing the producers that wanted to option his novel to let him do it. Released in 1957, Jack Arnold’s masterpiece is a landmark of 50’s sci-fi, filled with ingenious special effects and a closing speech that add to a powerful emotional ending that still catch viewers by surprise.
