I remember a movie from the 80s where a beam emitted from an observatory with a cyclotron within it, reduced objects of any size, remember that the main actor was a spy or something, and the actor in the role of evil held a tarantula spider in her hand covered by a black glove
I remember a scene from the movie an aircraft carrier ship after being reduced by the beam of particles is shown on the screen as an exact scale model of it produced by the reducing action of the beam particles
The actor in the role of villain in the movie that I remember was Clive Revill, that's the only data I remember.
I saw this movie on television in the late 80s, the translated title that should not be the original name was
"There was once a spy"
