David Harbour Denies Dropping Major Avengers: Doomsday Spoiler

Actor David Harbour has refuted claims that he revealed a significant spoiler for the upcoming Marvel film Avengers: Doomsday. An earlier report suggested that Harbour, reprising his role as Red Guardian, had stated his character would utter the line, "You... are Tony Stark," in a Russian accent. This line was interpreted as a major plot point, hinting that Doctor Doom's face beneath the mask would be that of Tony Stark, and that Red Guardian would be present for this revelation.

Harbour's initial comments were made in response to a request to recite a line from the movie out of context. However, in a subsequent interview, he clarified that the widely reported line was fabricated. He stated that the line he actually provided was, "Five, four, three, two, [one]." He emphasized that he does not say the "Tony Stark" line in the film and expressed surprise at the speculation, noting that a castmate had sent him an article suggesting he had "ruined the movie."

While Harbour's clarification addresses his involvement, the possibility remains that another character might deliver the "You... are Tony Stark" line, or that the initial report was mistaken entirely. The exact nature of the spoiler remains unclear, but Harbour confirmed that his countdown is indeed a significant moment in the film.

The revelation of the face behind Doctor Doom's mask is anticipated to be a major plot point, whether it occurs in Avengers: Doomsday or the subsequent Avengers: Secret Wars. Speculation suggests that key Avengers characters like Steve Rogers, Thor, or Bruce Banner, or even Spider-Man, might be the primary reactors to such a shocking reveal, given their connection to Tony Stark.

Directors Joe and Anthony Russo have previously stated that fans should prepare for a "very surprising ending" to Avengers: Doomsday. They described the film as having a "focused propulsive narrative" and indicated it would be one of the studio's longer films, potentially clocking in around two and a half hours. The directors have teased that the film's conclusion will be unexpected, setting the stage for Avengers: Secret Wars.
