LOKI Writer Michael Waldron Explains His Contributions To AVENGERS: DOOMSDAY And SECRET WARS Scripts

Doctor Strange in the Multiverse of Madness writer Michael Waldron has reflected on his role in shaping the next Avengers movies, and how he's been helping the Russo Brothers on Doomsday and Secret Wars...

The next Avengers movies were originally set to be released this year, with Jeff Loveness (Ant-Man and The Wasp: Quantumania) writing The Kang Dynasty and Michael Waldron (Doctor Strange in the Multiverse of Madness) tasked with Secret Wars.

Jonathan Majors' personal and legal issues, combined with the largely negative response to the Ant-Man threequel, saw Kang the Conqueror dropped as the MCU's next big bad. Both Loveness and Waldron were supposedly removed from their respective movies, but only after Waldron had been tasked with rewriting what then became "Avengers 5." 

Along the way, it became clear to fans and Marvel Studios President Kevin Feige that entrusting the relatively inexperienced Rick & Morty scribes with the Multiverse Saga's final chapters perhaps wasn't the wisest move. 

Still, of the two, Waldron had made a bigger impact on the MCU, having worked on Loki Season 1 and the Doctor Strange sequel, two projects which went a long way in establishing the MCU's version of the Multiverse. 

The return of directors Joe and Anthony Russo and writer Stephen McFeely is bound to have led to some major changes, with Robert Downey Jr.'s introduction as Doctor Doom obviously among the biggest. How many of Loveness and Waldron's ideas will make it into Doomsday and Secret Wars? That remains to be seen, though we recently learned that the latter has been lending McFeely a helping hand.

Talking to The Wrap, Waldron reflected on his Avengers journey and his current involvement with the two-part Multiverse Saga finale.

"I was writing the movie after that but there wasn’t a filmmaker attached yet, I was just involved in all those conversations," he said. "When that movie went away, I was working on what would become 'Avengers: Doomsday' and 'Secret Wars' for a time, and then they brought in the Russos and Steve McFeely."

"As those guys got in and wrapped their hands around what these movies were going to be, and [then] there was an opportunity for me to to come back in and get to know Joe and Anthony and Steve and really just help however I could," Waldron added. "That’s what I’m trying to do is just support them."

We'd imagine that his role is mostly to help them figure out the Multiverse of it all, especially as Loki and Doctor Strange in the Multiverse of Madness introduced many complex ideas (including Incursions, which should be crucial to both Doomsday and Secret Wars). 

McFeely likely appreciated Waldron's help, as he won't be joined by his Captain America: The Winter Soldier, Captain America: Civil War, Avengers: Infinity War, and Avengers: Endgame co-writer Christopher Markus on either of the upcoming blockbusters. 

Avengers: Doomsday is set to be released on December 18, 2026, with Avengers: Secret Wars scheduled to arrive on December 17, 2027.

It's kinda hard to get excited in these two Avengers films with all the damage the Multiverse Saga did to the MCU.

If Doomsday is Infinity War with multiverses instead of planets and Secret Wars is Endgame with more madness in the multiverses, so be it.

these events feel like are written by 10 different people lol.

I mean, I get it, the more talent, potentially they can create a good script, but..... too many voices, most of the times dont end well.

I wish the writing OGs had a chance to participate in the writing process of these movies. Creative consultation, editing, even legit dialog. I would like t9 think that they may help create tighter stories with better pacing than we've received in the last couple years.

Waldron is not a great writer, or maybe I wasn't impressed with the outcome of the projects he was attached with. Worst being multiverse of madness, which is an excellently directed movie but a horribly written one.

That movie feels like a rick and morty episode, a bad one.

Cool , I’m glad he’s involved tbh…

Not only did Waldron help launch the Multiverse Saga via Loki , I still think his approach to it was perhaps the best one since he used the concept to examine the characters of Loki in the series aswell as Strange in MoM so if he can do that in these 2 epic blockbusters then I think we should be good.

He seems to be brought on as a consultant moreso then anything so they might be prescribing to his rules for the Multiverse that were in Loki and MoM which I’m down for tbh.

Anyway , I’m cautiously optimistic for both Doomsday & SW so hope they turn out well!!.
