Marvel’s Maximoff twins are about to gain an especially strange bit of behind-the-scenes symmetry. Ruaridh Mollica, who joins VisionQuest as Tommy Maximoff, has said that a previous audition for Marvel was actually for the role eventually played by Joe Locke: Tommy’s brother, Billy, in Agatha All Along.
It is the sort of casting near-miss that makes a franchise built on alternate identities, transferred memories and magically displaced family members feel almost suspiciously on-theme. Mollica first knew he had auditioned for a different Marvel part but could not recall exactly which one. After finding the audition material again, he realized it had been for Billy.
“I found the dummy sides and it was actually Joe Locke’s part. It was the other twin, isn’t that mad?” Mollica said.
Paul Bettany, who returns as Vision, gave the coincidence an appropriately concise verdict: “It was always meant to be.”
From an audition for Billy to Tommy’s MCU arrival
The distinction matters because Billy and Tommy are not merely two characters sharing a family name. They are Wanda and Vision’s twin sons, and their stories are now being spread across the interconnected trilogy that began with WandaVision. Locke plays Billy Maximoff in Agatha All Along, described as the trilogy’s second series. Mollica’s Tommy enters in VisionQuest, which is positioned as its conclusion.
For viewers keeping track of the family tree, Mollica was close to entering the story through one twin and is instead arriving through the other. That does not mean the parts are interchangeable: casting decisions are made around the requirements of a particular role, and the performers now occupy separate corners of the same family narrative. Still, the reveal gives the pairing a satisfying accidental logic. The actor who once read for Billy will now play Tommy opposite Bettany’s Vision.
In practical terms, it also makes VisionQuest the project where the Maximoff twin storyline moves from a tease toward an on-screen reunion of ideas, if not necessarily a simple reunion of people. At the end of Agatha All Along, Billy uses his abilities to place Tommy’s soul into a dying boy. That development signals Tommy’s entrance while immediately making questions of identity central to his return.
Why identity is the key word for VisionQuest
VisionQuest follows White Vision after he received the original Vision’s memories. The series has a deliberately complicated emotional engine: memories can tell White Vision what the original Vision knew and experienced, but the show’s premise leaves open what those memories mean to the being who now possesses them.
That is an important difference between memory and identity. Memory is the stored record of experiences, relationships and knowledge. Identity is the larger question of whether those experiences, and the continuity they imply, make someone the same person. The series is set to explore that gap as White Vision tries to reconcile what the implanted memories mean for who he is.
Tommy’s arrival gives that question a family dimension. He and Vision will work out who they are to one another, rather than simply taking the answer for granted. The premise does not establish an easy father-and-son status quo; it establishes two figures whose connections must be understood amid unusual circumstances. That makes Mollica’s casting a narrative fit beyond the amusing Billy audition story: Tommy is arriving in a series concerned with whether relationships survive radical changes in form, memory and circumstance.
There is also a clear structural reason that the trilogy format matters. WandaVision established Wanda and Vision’s family story. Agatha All Along continued it through Billy, while ending with Tommy’s soul being placed into a dying boy. VisionQuest is now set to bring Tommy into direct contact with Vision while completing the three-series arc. Anyone wanting a refresher on the relevant characters can start with this essential viewing order for Vision, Wanda, Ultron and the Maximoff twins.
What has been established about the new series
The confirmed setup extends beyond the family story. White Vision will be dealing with Stark A.I.s and Ultron as he attempts to understand his own identity. The series also places him on the run from a mysterious bounty hunter.
Those elements make technology part of the show’s personal drama rather than just background lore. An A.I., or artificial intelligence, is a programmed system capable of processing information and making responses within its design. In this story, the presence of Stark A.I.s and Ultron connects White Vision’s private question—what do inherited memories make him?—to other artificial beings and systems. The supplied details do not specify their exact roles, objectives or relationship to White Vision, so it would be premature to assume whether they will be allies, adversaries, or something less clear-cut.
Likewise, “mysterious bounty hunter” establishes pursuit without explaining the hunter’s employer, target or motive. What is known is that White Vision is running while navigating the consequences of carrying the original Vision’s memories. That external pressure should give the internal identity conflict immediate stakes: he is not only trying to determine who he is, but doing so under pursuit.
A casting coincidence that suits the story
Mollica’s rediscovered audition sides are a small production detail, but they land unusually well because the twin connection is so central to this corner of the Marvel universe. In a more ordinary ensemble, an actor nearly being cast as a different character might be trivia. Here, it becomes a neat parallel to a narrative full of adjacent selves: one twin is played by Locke, while the actor who once auditioned for that twin now plays the other.
It is worth keeping the scope of that coincidence clear. Mollica did not say he was cast as Billy, only that the old audition material was for the role Locke ultimately received. The revelation does not change Locke’s role in Agatha All Along or the established story of Billy. It simply adds a new perspective to Mollica’s path into the franchise and underlines the close connection between the two series.
For Mollica, the move from a forgotten Marvel audition to Tommy Maximoff is a full-circle career moment. For the audience, it offers an unexpectedly fitting prelude to a series in which the meaning of family cannot be separated from the question of who, exactly, each person is.
When VisionQuest arrives
VisionQuest begins on Disney Plus on October 14. Its central setup is already clear: White Vision carries the original Vision’s memories, Tommy Maximoff enters the story, and the two will try to understand their relationship while White Vision faces Stark A.I.s, Ultron and a bounty hunter pursuing him.
How those threads resolve remains to be seen. But one thing is now delightfully straightforward: the actor bringing Tommy to the screen once read for Billy, making the Maximoff twins’ next chapter feel a little more destined than anyone could have planned.
