John Romita Jr - who provided artwork for the comics series - was said to be developing the segment for director Jeff Wadlow, but has now downplayed such reports.
"There was discussion with Jeff Wadlow about possibly doing something for the sequel," the artist told ComicBookMovie. "He mentioned it early on when he was first picked and no-one knew.
"[We] had an early conversation via email that 'he would love to do something like that in the second film', it hasn't gone any further than that. All I said [in an earlier interview] was that the director had discussed it and nothing was decided on."
Romita did confirm that he is in talks to become directly involved in the project in a different capacity, but did not reveal specific details.
"Now, there is something that he's asked me to do, that I can't discuss, that's not an animated sequence but (requires) artwork to be done," he teased.
"Again, that could change - there's still a year before that film comes out, who knows what they could throw into it.
"Right now, whatever he has me doing is not an animated sequence."
