Did David Harbour Spoil Tony Stark's Return in 'Avengers: Doomsday'?

Marvel fans are buzzing after actor David Harbour, reprising his role as Red Guardian, appeared to let slip a significant secret about the upcoming 'Avengers: Doomsday'. During an interview with Variety, Harbour was asked to deliver a line from the film out of context. He responded in character, with a Russian accent, "You are... Tony Stark."

The comment immediately raised questions, as reports indicate Robert Downey Jr. will return to the Marvel Cinematic Universe in 'Avengers: Doomsday' not as Iron Man, but as the iconic villain Victor von Doom, also known as Doctor Doom.

This has led to widespread speculation about why Harbour's character would address someone as Tony Stark. The simplest explanation is that Harbour was joking or intentionally misleading fans. Marvel Studios is known for its rigorous efforts to protect plot secrets, making it difficult to ascertain if this was a genuine spoiler.

Further fueling fan theories are subtle details from the film's trailer. Some viewers have pointed out that the character shown as Doctor Doom appears to have blue eyes, contrasting with Robert Downey Jr.'s brown eyes. Additionally, minor differences have been noted between the Doctor Doom costume displayed at different events. These observations have led to theories suggesting the film might feature multiple versions of Doctor Doom, or that Downey's Doom could be replaced or killed by another incarnation.

Speculation on platforms like Reddit ranges from Red Guardian mistaking Doctor Doom for Tony Stark without his mask, to a more complex multiverse plot where Doom is a variant from another universe, or even takes over Stark's body. Some fans, however, believe Harbour's comment was a deliberate, controlled leak by Marvel.
