Production for Avengers: Doomsday, the fifth Avengers film that will release Robert Downey Junior’s Doctor Doom on the team, started production in March of 2025. The film features a massive cast of actors that will appear, which you can review at the bottom of this page, and one of them just started their part in the process.

Anthony Mackie who plays Sam Wilson/Captain America is on his way to the set of Avengers: Doomsday. In an Instagram story post, he snapped a picture of himself with an ominous caption that simply read, “And so it begins…” The actor was wearing a Power Puff Girls t-shirt with the classic cartoon characters on it, but the ominous part about his post was the filter he used. Fake blood splattered the image of himself possibly hinting at the darker tone of the film and the amount of violence that will be showcased in it.
