The VHS Cover
Am I the only one who was creeped out by this while wandering the horror section of video stores as a kid? Seriously that image of the Leprechaun half-hidden in darkness holding a gleaming candle has never left me. Very effective, and hilarious in hindsight knowing it's not actually a scary film at all. As I child I was always curious why the fancy lady on the back was being friendly with the killer Leprechaun haha
Love the tagline too.
