It really is time for some HD or modern nuke bomb footage. It’s amazing people are still terrorized by such ancient fakery.
This is hilarious. Watch carefully this (purportedly real) A-bomb test footage, from 5:17 onwards – and find “the magician behind the curtain”.
Hint: we can see the studio cameraman (his head and hand) behind the mushroom cloud…
