While McFeely remains onboard to pen the script, Markus will not be contributing toAvengers: DoomsdayorSecret Wars. Joe Russo explained that McFeely is leading the charge on the writing front: “Stephen McFeely is writing the script,” confirming that only one-half of the dynamic writing duo is involved. Despite the change in the creative team, though, the Russos explained that their creative process itself hasn’t actually changed, while emphasizing that longstanding partnership with McFeely:

“We’ve always worked very closely with Markus and McFeely through all the work that we’ve done together.”

Joe Russo added that they continue to work closely with McFeely and Marvel Studios: “It’s a little bit like getting back on a bike. We have a really codified process that we all work together through… It’s very complicated to iron out a story of this scale.”
