Here is a vintage Youtube video of Media Entertainment’s promo to video stores and other video vendors to promote the home video release of A Nightmare on Elm Street 3: Dream Warriors.
The first two Nightmare film had little national recognition and were largely a grassroots phenomenon. Nightmare 3 was the first time it was heavily marketed to the audience and the result was both a higher grossing picture but also an overexposure of Freddy Krueger that doomed the series until Wes Craven’s New Nightmare.
