Not only was the script for The Conversation completed in the mid-1960s (before the Nixon Administration came to power) but the spying equipment used in the film was discovered through research and the use of technical advisers and not, as many believed, by revelatory newspaper stories about the Watergate break-in.
Ne samo da je scenarij filma dovršen sredinom šezdesetih (prije nego što je Nixonova administracija preuzela vlast), nego je i oprema za nadzor korištena u filmu otkrivena tijekom istraživanja tehničkih savjetnika, a ne, kao što su mnogi vjerovali, preko novinskih priča o Aferi Watergate.
