the movie shown is Godzilla 2014.
the music would be much different and would have footage of not just Hiroshima, but also of the cold war, afganistan, the SAS embassy siege, ect.
Timezones lore is heavily connected to the Afghanistan war and several other historical events. Hiroshima and Nagasaki was responsible for the birth of the failed experiments we encounter in TimeZone like the Seekers or Watchers in 1945. the assassination of JFK was the beginning of the SCD(spiecial crimes department). the iranian embassy siege(S.A.S) had the SCD helping the S.A.S. it wasnt just the SAS and terrorists during that siege in the TimeZone universe. theres a shitton of events in timezone connected to real world.
