You could have written your number on the warranty card and waited for Harlan Ellison to call you on his landline. You might have to stay up until 3 AM but it would have been worth it.

I think the trick to getting a call back from Harlan Ellison would have been subtly provoking him. "I bought your VHS so the least you could do is sign it. You kind of owe me now. Are you sure you even wrote this movie? I heard it was an original idea by Schwarzenegger."
