Ghostwatch was ridiculous. Anyone that believed it was real is an idiot. Not only did have at least 2 known actors in it it said "A Screen Two drama presentation" at the beginning and "Written by...." at the end.
Let's assume someone watching assumed it was real. Perhaps they missed the opening 30 seconds, so there goes seeing the production name. No one really reads credits, so no seeing the writing credit. Also the known actors were doing more presenting roles, were they not? Not outside the realms of possibility it fooled people. Don't forget, people were fooled into thinking Orson Wells War of the World's was real.
