Kan det här vara Dimension 5 ?
Spionens huvudperson har en tidsresanhet:
What happened? What was that device? Did he teleport? No, in fact he time-traveled. Which is later explained as travel to another dimension, "the fifth dimension." Not explained: why they skipped the fourth dimension, or how dimensional travel equals time travel.
Det gjordes 1966, så det passar din tidsram.
Fiendens spioner var från Sydostasien, tror jag, inte Ryssland.
