David Harbour has seemingly confirmed the Avengers: Doomsday Tony Stark reveal that Marvel spent two years declining to discuss. Asked by Variety to recite a line from the film out of context, he offered one in his Red Guardian voice, finger pointed: “You… are Tony Stark.”
Warning! Potential Avengers: Doomsday spoiler follows:
“You… are Tony Stark.”

The line does two things. It suggests Doctor Doom removes the mask at some point in the film, and that Red Guardian is in the room when it happens. It is also a neat inversion of Robert Downey Jr.’s “I am Iron Man” — the line that ended Tony Stark’s MCU run in Avengers: Endgame.
The Avengers: Doomsday Tony Stark reveal, explained
Fans had argued over whether the unmasking would be saved for Avengers: Secret Wars. Harbour’s answer points to Doomsday itself, assuming he was not simply trolling an interviewer, which remains a possibility. IGN and Entertainment Weekly both read the exchange as confirmation of a major story beat.
If the line is genuine, the resemblance has a multiversal explanation. Doctor Doom comes from Earth-828, the reality introduced in The Fantastic Four: First Steps, and may be that universe’s version of Tony Stark — a theory tbreak covered when the trailer landed.
There is an irony in Harbour being the one to let it out. The film was reportedly shot without a full script — Sebastian Stan has said he has no idea what happens — yet the actor playing a Russian supersoldier appears to know exactly when Doom’s helmet comes off.
