Mike Grell is a legendary comic book writer and artist, having started his work at DC Comics in 1973. While Grell has worked on almost every major character for both Marvel and DC, he is perhaps best known for his groundbreaking reboot of Green Arrow, “The Long Bow Hunters,” which was the second “prestige format” book published by DC after Frank Miller’s The Dark Knight Returns. Grell’s work on Green Arrow was the basis for many elements in the The CW’s Arrow series — in which Grell also had a cameo in the pilot episode.
