Este rascunho de script anterior indicou que ele era um renomado físico nuclear:
No entanto, há muitos detalhes nesse roteiro que não combinam com o filme finalizado, pois ao invés de Doc ser um inventor solitário e excêntrico nos anos 50, quando Marty foi para a mansão de Doc no passado, ele o encontrou hospedando um pretensioso A festa flanqueava duas lindas mulheres, e Doc surge com a ideia do "capacitor de campo temporal" quando ele sussurra algo no ouvido de uma mulher e ela bate na cabeça dele com uma garrafa de cerveja. Mas haverá uma nova série de histórias em quadrinhos de Volta para o Futuro, coescritas por Bob Gale (que escreveu os filmes originais com Robert Zemeckis), e com detalhes sobre os bastidores dos filmes, como Gale descreve em esta entrevista :MARTY Doc Brown's all right — he's just a little hung up on time. A couple of years ago, he showed up at my house and hired me to sweep out this garage of his. He pays me 50 bucks a week, gives me free beer... and gives me total access to his record collection — he's got this great old record collection.

Hard to believe he was one of the world's greatest nuclear physicists.
I said, "If we're going to do this, let's go back to the characters. Let's do stories suggested by the movies, by the characters. People have always asked how did Mary and Doc first meet? That's a good story. Let's do that in the first issue. People have asked, how did Doc Brown's house actually burn down? Was it a fire insurance scam? What was that? In issue #2 we tell that story. Issue #3, people have asked, wouldn't have George and Lorraine wanted to find out what happened to Calvin Klein? Well, we deal with that in issue #3.
These are all things that are suggested by the movies, suggested by people thinking about the world of the movies, and I think that our fans are going to be very very happy with the way these things are turning out. I certainly am. These comics are exceeding my expectations. Again, the people at IDW said, "Can we say that these are canon," which is always something that makes me crazy. It's fiction. How can it be canon? I said, "Look (and we actually have a text piece in the first issue talking about this) when you have a time machine and infinite time lines everything is canon, so, yes, it's all canon and none of it's canon."
E, de acordo com este artigo , o O primeiro número mostrará que o Doc trabalhou no Projeto Manhattan para construir a primeira bomba nuclear:
For example, the first issue’s stories will uncover the origins of how Doc Brown and Marty met each other, and cover Doc’s work on the Manhattan project during World War II.
Então, mesmo que ele não fosse famoso como um dos maiores físicos nucleares do mundo, acho que podemos especular que ele provavelmente tinha pelo menos um Ph.D. na física, assim como outros jovens físicos que trabalharam no Projeto Manhattan (já que Doc deveria ter apenas 30 anos em 1955, ele teria 20 e poucos anos nos últimos anos da Segunda Guerra Mundial), como Richard Feynman .
