Robert Downey Jr. is on track to become the highest-grossing actor at the box office following the release of Avengers: Doomsday, scheduled for 2027. Known for his transformative role as Iron Man in the Marvel Cinematic Universe, Downey Jr.’s remarkable box office success has already positioned him near the top of Hollywood’s most lucrative stars.
Robert Downey Jr.’s Rise as a Leading Box Office Star
After 2008, Robert Downey Jr. established himself as a top Hollywood star with his iconic performance in Iron Man, elevating his career and generating substantial box office returns. His repeated appearances in Marvel films have solidified his status, contributing to $12.1 billion in box office earnings from his MCU movies alone. This figure makes up the majority of the $14.3 billion accumulated from films where he took a lead or lead ensemble role. These earnings far surpass many of his contemporaries.
Current Standing Among Hollywood’s Highest-Grossing Actors
Across his career from 1983 to 2025, Downey Jr. has appeared in films totaling $16.2 billion at the box office. Of this, $14.3 billion comes from his leading roles, which places him ahead of stars like Chris Pratt, Tom Cruise, Dwayne Johnson, Tom Hanks, and Johnny Depp. Despite this impressive record, Downey Jr. currently ranks just behind fellow Marvel stars Zoe Saldaña and Scarlett Johansson, who hold the top two spots as highest-grossing actors.
Zoe Saldaña leads with a total box office return of $15.6 billion, driven primarily by her roles in Avatar and Guardians of the Galaxy, while Scarlett Johansson is second with $15.4 billion, boosted by her role as Black Widow. Samuel L. Jackson is listed third with $14.6 billion; however, much of his total includes Avengers: Endgame’s massive haul, despite his limited screen time in that film. Adjusting for that, Downey Jr. would likely surpass Jackson to be the third highest-grossing actor already.
Avengers: Doomsday Offers a Clear Shot at the Top Spot
Avengers: Doomsday is set to be a pivotal moment for Robert Downey Jr. as it could push his box office total beyond Zoe Saldaña’s record. At present, Downey Jr. trails her by approximately $1.3 billion, but every previous Avengers film has exceeded that amount, suggesting Doomsday’s opening could surpass those benchmarks.
This upcoming release holds even greater significance due to the likely absence of major MCU stars who currently top the rankings alongside Downey Jr. Samuel L. Jackson’s return as Nick Fury remains unconfirmed and, if he does appear, his role is expected to be minimal, likely excluding him from being counted as a lead. Scarlett Johansson has consistently ruled out reprising her role as Black Widow, diminishing her potential to increase her box office total with this film.
Similarly, Zoe Saldaña’s character Gamora is not anticipated to be part of Doomsday, as the narrative no longer centers on the Guardians of the Galaxy in the same way. The absence of these key figures positions Downey Jr. uniquely to surpass them if Avengers: Doomsday performs as expected.
Potential Challenges and Industry Implications
Despite the optimistic projections for Doomsday, there remain uncertainties. The film’s box office performance will need to be strong to secure Downey Jr.’s top position, and any unexpected box office failure could prevent him from breaking the record. Additionally, competitors like The Super Mario Galaxy Movie could potentially outgross Doomsday by significant margins, complicating Downey Jr.’s path to number one.
Still, the combination of Downey Jr.’s ongoing presence and the relative absence of other leading MCU stars creates a rare opportunity to rewrite Hollywood’s box office history. Should he succeed, it would mark an extraordinary milestone in his career, reinforcing his legacy as one of the most influential actors of his generation.
A Look at the Avengers: Doomsday Cast
The film features a robust ensemble, including Chris Hemsworth as Thor, Vanessa Kirby portraying Sue Storm / Invisible Woman, Joseph Quinn as Johnny Storm / Human Torch, and Ebon Moss-Bachrach taking on the role of Ben Grimm / The Thing. These characters contribute to the film’s appeal and are expected to attract a wide audience eager to see how the story unfolds.
