In the "Ultimate Fantastic Four Vol. 1" hardcover edition, Millar and Bendis write about the somewhat odd circumstances of their collaboration. Foremost, virtual communication was the only method available as Millar lives in Glasgow, Scotland, and Bendis in Portland, Oregon. Secondly, they both had considerably different writing styles, as Millar's stories are typically fast-paced and widescreen, while Bendis' output is more dialogue-heavy and slow-paced and both writers feared it could wreck the project. It was agreed that Millar would write the plot and Bendis finalized the scripts based on his plots.
