text: This is a 1972 Disney movie. For the time, I was eleven years old and I thoroughly enjoyed this movie. Feeling nostalgic, I purchased the three series DVD's of the Dexter Riley movies and even now, at age 46, I still enjoyed them. It was all about fantasy, magic, and clean fun. And it still is! I wasn't sure which of the three movies came first then second and last. So now I have the official dates. On December 31, 1969 The Computer Wore Tennis Shoes--On July 12, 1972 Now You See Him Now You Don't--On February 6, 1975 The Strongest Man In The World. I still think the middle movie was the best. The special effects were amazing back in 1972 to us kids. I definitely recommend it to all ages.
