Following The Amazing Colossal Man, Mr. BIG switched things up (sorta) by putting out a movie about smallified people rather than embiggoned ones. However, as this follows the path set down by Dr. Cyclops, it also features the doll-sized folk being menaced by a (comparatively) gigantic regular man and dog. Therefore, the difference is somewhat academic.
Fans of giant props to represent mundane things like humongous pencils and telephones are the most likely to be entertained. Heck, Irwin Allen built an entire TV show around basically the same premise. One can only assume all the expensive looking giant props on display here were left over from the previous year’s Incredible Shrinking Man.
I have to admit, I haven’t seen this since I was a kid, and I don’t remember it getting nearly as much play on TV as the other Gordons of this period. The cast is headlined by the reliably stolid John Agar, with a much more sympathetic performance of busy character actor John Hoyt as the guy who smallifies everyone. I remember his character being more of the tragic variety rather than the evil jerk from Dr. Cyclops.
