Before ABC aired the film on November 20, 1983, anti-nuclear activists Josh Baran and Mark Graham obtained a bootleg copy secretly provided by Meyer. They duplicated and circulated it among peace organizations, then organized screenings in homes, bars, restaurants, and community spaces under the title The Day Before. Each screening was followed by discussions, town meetings, and interviews with peace leaders, while private showings were arranged for Time, The New York Times, the BBC, members of the British House of Commons, and even the Pope. The campaign effectively bypassed ABC's official publicity strategy and generated such intense advance interest that rumors the network might shelve the film became harder to sustain. Variety later called the operation “the greatest PR campaign in history,” while scholars described it as an early example of attaching a public-issue movement to a commercial media release.
