How we track the cast
We monitor the confirmed cast’s public Instagram and X accounts, plus verified trade reporting, for training photos, location tags, wrap posts and cryptic teases, then report what a post actually shows, never more. David Harbour teasing a Tony Stark line is a good example: the quote is real, the meaning is our read.
What happens next
As Secret Wars casting firms up, this tracker grows. For the movies themselves see the Avengers: Doomsday guide and the MCU release calendar. Which confirmed name are you most excited to see share the screen? Tell us below.
