Jon Favreau Revealed Why He Secretly Recorded Robert Downey Jr. And Gwyneth Paltrow's Conversations Off-Camera During Iron Man (2024)

In its earliest days, the MCU was not the well-oiled machine that fans have come to know and love. It was a disorganized band of misfits all working together to bring a fun movie to the big screen. That movie was Iron Man, and despite everything working against it, the film was a resounding success that fans still love.

Jon Favreau was the filmmaker behind Iron Man, and the director has opened up about some unconventional methods he used while filming, including what turned out to be a genius strategy that helped make the film a smash hit.

Jon Favreau Tracked Conversations Between Robert Downey Jr. And Gwyneth Paltrow, Which Helped Shape Iron Man

While making Iron Man, Jon Favreau was navigating through uncharted waters. After all, Iron Man was hardly an A-list character, and Robert Downey Jr. was in a drastically different place in his career. With this in mind, Favreau used every trick in the book to bring the film to life, even using a bold strategy that helped shape character interactions in the film.

"I was a very good student where I would take notes as they would talk, and whether it was improvising or even just talking about the scene, I would write stuff down that they would say," Favreau said in an interview.

In that interview, Favreau pinpointed a particular interaction of theirs.

Per The Hollywood Reporter, Gwyneth Paltrow corrected RDJ "because we were reading the script and it said, ‘This looks like Jackson Pollock’s spring period.’ And then she corrected us in rehearsal. She says, ‘No, it’s actually The Springs period. The Springs is the part of the Hamptons where Jackson Pollock lived and worked, not spring, not the season.'"

"So I wrote down every word, and she’s correcting him in the movie when he says, ‘the spring period.’ So it just adds to their sort of nippy banter. I find it thoroughly compelling and entertaining to watch the two of them onscreen together because they had this banter that has an edge to it," Favreau added.

It's such a simple, yet effective technique, and it worked brilliantly, as Iron Man changed the game.

Released in 2008, Iron Man was a massive hit that no one saw coming. It garnered rave reviews, and it helped get Robert Downey Jr. back in the spotlight. Favreau's adept direction, coupled with Downey Jr.'s charismatic portrayal of Tony Stark, propelled Iron Man to box office glory, grossing over $585 million worldwide.

Of course, there's no way to discuss the success of Iron Man without noting that it started the MCU. Say what you will about how Phase 4 and Phase 5 were handled, but the first three MCU Phases were beautifully structured. So many movies and shows that all helped tell a connected narrative, culminating in Infinity War and Endgame, two of the biggest and most successful films of all time.

Iron Man was the one that started it all, and to this day, it's considered one of the best comic book movies ever.

It's a major feather in Favreau's cap, and the man has had a wonderful career as a filmmaker.
