New Nightmare (1994)

It's nearing the 10th Anniversary of the film 'A Nightmare on Elm Street' and one of the stars, Heather Langenkamp, is being scared by a voice on a phone, sounding very similar to the film's villain, Freddy Krueger. When Heather realizes that Freddy has now entered the real world, the only way to defeat him is to become Nancy Thompson once again.
