.l.Iron Man 4 (2025) - First Trailer - Robert Downey Jr, Katherine Langford - Concept

🦾 Iron Man 4

For years, fans believed Tony Stark’s story had ended with his heroic sacrifice in Avengers: Endgame. But speculation is running wild once again with whispers of Iron Man 4 — a project that could see Robert Downey Jr. return in some form alongside Katherine Langford, whose deleted role as Tony’s daughter, Morgan Stark, has long fascinated fans.

Rumors suggest Iron Man 4 would not undo Tony’s sacrifice but instead continue his legacy through Morgan. Katherine Langford, originally cast as an older version of Morgan for Endgame’s dreamlike “Soul World” sequence, is said to be eyed for a full return.

The plot might follow Morgan as a young woman struggling with the shadow of her father’s legacy — and possibly inheriting a version of the Iron Man mantle. Insiders claim Robert Downey Jr. could reappear through holograms, flashbacks, or even as an A.I. modeled after Tony, guiding his daughter as she steps into the armored future.
