I was quite young when I saw the 1971 film Andromeda Strain in the theatre, and the image of the monkey dying when exposed to the organism still bothers me.
It certainly looked traumatic and the monkey appeared to die, but I have no idea how real that was.
These days films with animals usually contain a "No animals were harmed..." at the end, but this was way before that.
Question: Did they torture and kill a monkey during the filming of Andromeda Strain? If not, was it file footage of something like that, or was it some type of convincing special effect?
Here is a clip with the scene in question, it looks real to me, watch it at your own discretion
