Episode 2 of She-Hulk: Attorney At Law took full advantage of the self-awareness of the series in order to crack wise about Mark Ruffalo replacing Edward Norton as Bruce Banner/The Hulk. As Jen finds herself working on Emil Blonsky’s case, she also finds herself conflicted given Blonsky’s past with her cousin. Smart Hulk gives her the all clear, however, telling her he is a “completely different person now, literally.” It was a great joke for those who caught it and it was never thought of again…until now.
In an interview with The Direct, She-Hulk director Kat Coiro revealed that the show almost went one step further than the subtle nod to Norton’s time as the Hulk: they almost brought him back for a cameo.
There was a lot of talk about the fact that the last time they were together a different actor was playing the Hulk. And Mark [Ruffalo] made quite a few jokes about that. And we did entertain the idea of swapping Mark out for Edward Norton. But that did not come to pass.Kat Coiro
Obviously, it never got past the idea stage, but given the crazy nature of the ending, which saw She-Hulk in the writer’s room of her own show, talking to Marvel Studios K.E.V.I.N. and altering the plot of the finale, it would have fit and been a fantastic bit of fun. Of course, there’s no guarantee that Norton would have agreed to the appearance, but knowing that it’s been considered once could leave the door open for them to eventually approach the actor for a return in another project. With Avengers: Secret Wars on the way, anything is possible.
