How a 2005 Comedy Paved the Way for Robert Downey Jr.’s Iron Man
Before Iron Man, Robert Downey Jr. starred in a little-known comedy that changed his career forever. Discover the film that convinced Jon Favreau he was perfect for Tony Stark—and why it’s a must-watch in 2025.
Many people credit Robert Downey Jr.’s Hollywood comeback to his role as Tony Stark, but his journey back to stardom actually began with a sharp-witted comedy released in 2005. Downey himself has called Kiss Kiss Bang Bang “the best film I’ve ever done,” and it was this performance that caught Jon Favreau’s eye, ultimately leading to his casting as Iron Man.
Downey’s Defining Role Before Marvel
In Kiss Kiss Bang Bang, Downey plays Harry Lockhart, a small-time crook who stumbles into an audition and lands the lead in a detective movie. Val Kilmer stars alongside him as Perry van Shrike, a private investigator who becomes Harry’s mentor. Michelle Monaghan rounds out the main cast as Harmony Faith Lane, and together, the trio gets swept up in a murder mystery that’s as hilarious as it is suspenseful.
Fans have recently revisited a standout scene from the film, one that many believe showcased the vulnerability and wit that would later define Tony Stark. Downey’s audition scene in the movie not only impressed the fictional filmmakers but also left a lasting impression on viewers and, most importantly, Jon Favreau.
Robert Downey Jr. says this movie is why he became Iron Man. On Kiss Kiss Bang Bang (2005), he’s said it’s “one of the best movies I’ve ever made” — when his career was hanging by a thread. Jon Favreau saw his life witty and vulnerable just like Tony.
Why Kiss Kiss Bang Bang Still Matters
Shane Black’s direction gives the film a unique blend of neo- noir and buddy comedy, making it a perfect pick for the holiday season. The story kicks off when Downey and Kilmer’s characters witness a body being dumped during a fake stakeout, pulling them into a fast-paced investigation. The film’s humor, action, and sharp dialogue keep the energy high from start to finish.
Downey and Kilmer’s chemistry is undeniable, and their off-screen camaraderie added depth to their performances. Kilmer even gave up drinking on set to support Downey’s recovery, a testament to their bond. Black’s script was carefully crafted to keep audiences engaged, with a new twist or thrill every half hour.
Despite its critical acclaim, Kiss Kiss Bang Bang didn’t make a splash at the box office, earning just $15.8 million on a $15 million budget. Still, it holds an 86% rating on Rotten Tomatoes, a 7.5 on IMDb, and a 73 on Metacritic. The screenplay is based on Brett Halliday’s novel Bodies Are Where You Find Them.
Downey’s Road to Redemption
Downey’s path to this pivotal role wasn’t easy. After a series of legal troubles in the late ‘90s, including a prison sentence, he struggled to find his footing in Hollywood. His appearance in Gothika in 2003 marked a turning point, but it was the script for Kiss Kiss Bang Bang that truly reignited his career.
The film almost didn’t happen—several studios passed on the project before Joel Silver agreed to produce it. Other actors like Benicio del Toro and Hugh Grant were considered for the lead, but Downey landed the part thanks to a recommendation from Susan Downey, who worked for Silver at the time. His salary was modest, reflecting the film’s tight budget, but the opportunity proved invaluable.
Downey’s performance in Kiss Kiss Bang Bang became his calling card, leading to his iconic role in the Marvel Cinematic Universe. He later helped director Shane Black secure a spot in the MCU, where Black directed Iron Man 3. Downey’s career has since soared, earning him an Oscar for Oppenheimer and a massive payday for Avengers: Doomsday.
A Cult Classic Worth Revisiting
Kiss Kiss Bang Bang remains one of the most underrated films of the 2000s, blending sharp humor, action, and heart. Downey’s signature sarcasm and charm shine throughout, offering a glimpse of the qualities that would later define his portrayal of Tony Stark. The film is now available to rent on Amazon and AppleTV, making it the perfect time to add it to your holiday watchlist.
