20 Most Watched Joe Rogan Experience Podcasts

While it might not have been the stereotypical, three-hour JRE episode that we've come accustomed too, when Hollywood icon Robert Downey Jr. popped up to promote his latest film, Doolittle, it was pretty much guaranteed that this was going to be one of the biggest episodes in the history of the podcast.

Although the film he was there to promote ultimately flopped, it certainly didn't take away from the conversation the two had with each other. While they engaged in the sort of philosophical and random chat that Downey does better than anyone else, the real gems came when Rogan probed him about possibly returning to the role of Iron Man in the future.

It's a role that he's most-loved for by fans and Rogan isn't afraid to ask the questions that we're all dying to know. Of course, Downey does exceptionally well and dodging whatever queries Rogan has about returning to the Marvel Cinematic Universe as Tony Stark, but he still gave us an interesting insight into the process that fans would only get from a one-on-one interview with someone like Rogan.
