When the three are frozen in the U.N.C.L.E. infirmary, the order of the beds from front to back is Neila, her father then Solo. After the attack begins Solo is suddenly in the middle bed and Dr. Nillson is in the far bed.
When Neila points and activates the suspended animation device at Inga, she tells Solo that she set the timer for 60 seconds. However, Inga comes out of it after only 42 seconds.
The unit being used to reanimate Solo and the girl is simply an oscilloscope which is normally used for TV and audio servicing. An alternating zero voltage flat line and a lissajous pattern are used.
When the suspended animation device was activated during the opening sequence, the music also stopped. It was established later that the device only affects living matter.
Opening sequence: in a state of suspended animation, the blonde in a blue dress blinks.
The wet leather straps around Neila's neck are supposed to shrink enough to put her in mortal danger, but they're clearly loose and the worse they could do is cause her mild discomfort.
During the battle, when Solo shoots his gun is "silenced" as are all U.N.C.L.E. guns with built in silencers, but even though Neila and Inga have the exact same guns, when they fire the shots are NOT silenced.
