Tom Holland has said the Marvel spoiler he most regrets revealing was Tony Stark’s death in Avengers: Endgame. The actor’s admission revisits his long-running reputation for accidentally disclosing plot details, and highlights the challenge Marvel faces in protecting major story developments.

Holland revealed the death while discussing Spider-Man: Far From Home on The Graham Norton Show in 2019, describing it as one of the consequences of Endgame. Although Endgame had already been released, the remark could still spoil the film for viewers who had not seen it; Holland later acknowledged that it was a mistake.
