More Original Art Stories: The Dark Knight Returns
"Here's what I remember of it. Klaus Janson was working Dark Knight and used Greg Brooks as a background inker*. Well Frank Miller gets wind of this and has a fit, something about the integrity of the project and letting an amateur put his hands on it. The end result was art for Dark Knight #1 and #4 went to Frank Miller and art for Dark Knight #2 and #3 went to Klaus Janson. Now here's an interesting bit, the original art never once came into the production department. It was sent to a printer for black and blue line copies on strathmore paper. Corrections were made by Bob (little fingers of lead) Rozakis on the printed blackplate; hence the famous Lois Lane flub in Dark Knight #1. As a production man Bob was a great accountant!"
* Klaus Janson apparently used a number of inking assistants on the Dark Knight series including a young Todd McFarlane. McFarlane worked on at least one issue, just filling in the blacks, or so Todd said in an interview in the mid 1990s, just after he announced the Spawn/Batman cross-over. I'm pretty sure that the mention was done in an interview with former Marvel editor Jim Salicrup, possibly for the now defunct Comic Interview magazine. Eventually I'll dig it out, but if anyone has the interview on hand then get in touch so I can make the proper reference (the interview is notable for foul language and also for the comments about the phone breaking down mid-interview). I'd be very curious to know if other artists have any recollections about working on that series.
