Rodan

THC had not thought about this movie for awhile but happened to stumble across something (see here) that brought it all back.

When THC was a kid, WOR-TV, Channel 9 in New York City ran Million Dollar Movie.  Every week the feature movie would be shown twice each evening and several times on Saturday and Sunday.  It was where I first saw Godzilla and King Kong.  Rodan created a sensation when it premiered on Million Dollar Movie.  Made by Toho Studios in Japan, Rodan was released in the US in 1957, and my guess is that it made its Channel 9 debut in 1958 or 1959.  I (and my friend Tim) thought Rodan was simply the best film ever made and watched it 5 or 6 times that week.  It must have attracted a good audience because it was featured several times thereafter on Million Dollar Movie.  Or maybe it was just cheap to show.  You can decide - here's the US trailer:

Rodan later went on to do a series of buddy films with Godzilla & Mothra.  You can read more about Rodan's powers and life story here.
