Alan Moore interviewed at his home in Northampton, England in early 2002 for Hotdog Magazine.
Alan Moore: [...] I do get some funny phone calls. Nicolas Cage phoned me up a few times because he likes my stuff. He seems nice enough, but the phoned me once to ask me for advice on his love life. It must be a lonely existence being a film star.He was asking me if he should choose this girl over another girl he was seeing.I just said, "I don't know." But I thing it worked out happily because he's not needed my advice since.
