While speaking to Brandon Davis, VisionQuest creator Terry Matalas revealed that he gave serious consideration to getting (well, asking) Robert Downey Jr. to cameo as Tony Stark.
Spoilers follow.
Of course, RDJ's new MCU character, Doctor Doom, made an appearance in the finale's surprise post-credits scene when he appeared to resurrect Wanda Maximoff (Elizabeth Olsen), but we don't know if that was actually Downey providing the villain's voice (it didn't sound like him), and nobody involved with the show has discussed the sequence yet.
As it turns out, Matalas wanted the Academy Award-winning actor to return as a pre-Iron Man Stark for a flashback scene with guest star Mary McDonnell (Katerina Wells). The showrunner says he didn't actually approach Downey in the end, as he realized it would have been a "big ask," but after meeting him, he thinks they probably could have made it happen.
In a separate interview with THR, Matalas was asked if he has had any conversations about "working on a future instalment of the MCU."
"I have to be careful what I say. I will say that we have so, so many ideas. And if I were having those conversations, there’s no way I could say that I was having those conversations. But who would not want to see this family again?"
He's having those conversations!
Vision and Wanda are both expected to appear in Avengers: Doomsday, but we probably won't see the full family reunion we're all waiting for until Avengers: Secret Wars - and even then, the Scarlet Witch may not be in control of her actions.
"When VisionQuest begins, Vision, rebooted and having escaped from those who sought to weaponize him, has been in hiding. Searching for new meaning, he consults the AI personas embedded in his programming, including F.R.I.D.A.Y., E.D.I.T.H., J.A.R.V.I.S., and the infamous Ultron. His discreet existence ends when a bounty placed on his head thrusts him on the run with Thomas Shepard, a mysterious boy who may be Vision’s son, reincarnate.
As Vision evades capture, he must confront his nature, resist Ultron’s influence, and unravel the enigma that is his young companion if he’s to survive.”
VisionQuest also stars Ruaridh Mollica as Tommy Maximoff/Speed and Thomas Shepherd, Todd Stashwick as Paladin, T’Nia Miller as Jocasta, Lauren Morais as Lisa Molinari, Orla Brady as F.R.I.D.A.Y., Diane Morgan as an associate of Paladin, Polly Frame, Henry Lewis as D.U.M.-E, Jonathan Sayer as U, Emily Hampshire as E.D.I.T.H., and James D’Arcy as J.A.R.V.I.S. Faran Tahir also reprises his Iron Man role as Raza, with Cristian Lavin and Mary McDonnell appearing in undisclosed roles.
The series is directed by Christopher J. Byrne, Gandja Monteiro, Vincenzo Natali, Terry Matalas, and written by Terry Matalas, Cindy Appel, Christopher Monfette, Nicole Falsetti, and Matthew Okumura.
