Die Hard 1988

@khawlah In which episode? I don't remember I've watched them all. The name "Hans Gruber" does sound familiar though. I think some friends talked about it when I was younger but I couldn't understand what they were talking about because I just watched the movie for the first time now at 19 years old, they watched it at way younger.

@binge-watcher The Supernatural episode, you mean? It's 2.18 Hollywood Babylon. When Dean quotes the movie and says "Come out to the coast, we'll get together, have a few laughs."
