Despite their mutual connection to technology and innovation, Robert Downey Jr. and Elon Musk don’t seem to share the same admiration for one another. In a recent interview, RDJ urged Musk to “control his behavior” amid ongoing controversies surrounding the tech billionaire. While Downey Jr.’s portrayal of Tony Stark in the Iron Man series has drawn numerous comparisons to Musk, the actor’s recent comments suggest that the real-life figure behind Tesla and SpaceX might be falling short of the ideal.
The Tony Stark-Musk Comparison

Tony Stark, the billionaire inventor from Marvel’s Iron Man franchise, has often been linked to Musk, who even made a cameo appearance in Iron Man 2. Director Jon Favreau once acknowledged that Musk’s visionary persona helped influence Stark’s character. “Musk gave us some insight into what it’d really be like to be Tony Stark,” Favreau remarked, further cementing the link between the fictional and real-life billionaires.
However, despite the parallels, RDJ seems unimpressed by Musk. Speaking on the On With Kara Swisher podcast, RDJ said, “I just wish that he would control his behavior a little more,” distancing himself from the comparisons that have circulated for years.

Downey Jr.’s Critique of Musk’s Conduct

While Robert Downey Jr. acknowledged Musk’s accomplishments, such as his ambitious goals for space exploration and his significant contributions to the tech industry, he was critical of Musk’s recent actions. RDJ specifically questioned Musk’s obsession with colonizing Mars, stating, “This idea of ‘It’s all OK because we’ve gotta get to Mars’ doesn’t really hold water with me”.
The critique aligns with a growing sentiment of concern over Musk’s increasingly controversial behavior, especially following his acquisition of Twitter (now X) and his political affiliations. Musk’s public support for Donald Trump and involvement in various right-wing controversies have sparked backlash, leading many, including Robert Downey Jr., to question Musk’s actions.
Musk’s Political Involvement and Public Persona

Musk’s public behavior has raised eyebrows, especially his vocal support for Donald Trump and participation in political rallies. In addition to being a significant force in the tech world, Musk has become increasingly vocal about his political beliefs, which has only intensified the scrutiny surrounding him. RDJ, while not directly addressing Musk’s politics, made it clear that separating personal behavior from accomplishments is becoming more difficult in today’s information age. “Separating the individual from their behavior is a tough thing to do,” he noted, adding that such behavior often divides people rather than fostering healthy discourse.
A Changing Relationship

Robert Downey Jr.’s critique of Musk reflects a shift from their earlier relationship. In the past, the actor and tech mogul shared some camaraderie, with Musk even allowing scenes from Iron Man 2 to be filmed at SpaceX. Over the years, however, Musk’s behavior seems to have distanced him from those earlier ties, with RDJ expressing a clear preference for more controlled conduct.
Despite the critique, he didn’t entirely dismiss Musk’s achievements, stating, “You have to look at all that [Musk has] done that demonstrates why he’s valuable”. This acknowledgment reflects the complicated dynamic between respecting someone’s contributions while critiquing their public behavior.
Final Thoughts

While Robert Downey Jr. may have once seen some of Tony Stark in Elon Musk, his recent comments suggest that the actor no longer identifies with the tech billionaire’s behavior. His advice for Musk to “control his behavior” reflects broader concerns about the CEO’s conduct, especially given his increasingly controversial public persona. Still, RDJ recognizes Musk’s significant impact on technology and innovation, leaving room for admiration of his achievements while advocating for more responsibility in his public actions.
