“Basically, when I take over something as a writer, I always try to work as closely as I can with the artists on the book, so I immediately did my best to strike up a friendship with Steve Bissette and John Totleben. I asked them what they would like to do in Swamp Thing … 

One of those early notes was they both wanted to do a character that looked like Sting. I think DC is terrified that Sting will sue them, although Sting has seen the character and commented in Rolling Stone that he thought it was great. He was very flattered to have a comic character who looked like him, but DC gets nervous about these things. They started to eradicate all traces of references in the introduction of the early Swamp Thing books to John Constantine’s resemblance to Sting. But I can state categorically that the character only existed because Steve and John wanted to do a character that looked like Sting.”
