From a 1968 Stars and Stripes interview with Shel Silverstein:
HAL: I understand that you are going to do a movie or want to do a movie. Can you tell us about it?
SHEL: I will be doing one soon. It’s a movie I wrote and will be directing. It will be very far out. It will be the furtherest-out movie ever done in America, I know that. In any country, as far as I know.
HAL: Will it be impressionistic or realistic?
SHEL: Yeah, impressionistic and realistic. Yet, never obscure. Always very clear.
Now, please note that Shel Silverstein never directed a movie… and was probably never actually going to. Was he just messing with his interviewer? Possibly. And how fun is that?—seeding the world with news of made-up projects. Maybe that’s how you decide what to actually do: wait and see which made-up project generates the most excitement.
Also, can I just remind you that Shel Silverstein looked like this?
