The April 6, 1958 Alfred Hitchcock Presents episode Disappearing Trick ends with the master of suspense making a plea to the people of the year 2000. A clip of the program can be seen below.
Since this program is on film and will probably be shown for many years to come, I should like to address my next remarks to those of you who are watching this show in the year 2000. Please write in at once and tell us what life is like. I'm quite curious. Until next week, good night.
