Here is the story of how a massive, real-life fanboy moment paved the way for an iconic on-screen rivalry—and the famous meta joke they collectively banned from the screen.
The Sherlock Paradox: Parallel Geniuses
In the late 2000s and early 2010s, the entertainment world witnessed a fascinating, parallel-universe development. In Hollywood, Robert Downey Jr. was redefining Sir Arthur Conan Doyle’s famous sleuth on the big screen as a bohemian, bare-knuckle-boxing action hero. Almost simultaneously, a relatively low-profile British actor named Benedict Cumberbatch was transforming BBC’s Sherlock into a global, internet-shattering pop-culture phenomenon.
Instead of generating a bitter rivalry, however, the situation sparked a massive mutual admiration society. Cumberbatch has never hidden the fact that he was a massive, starstruck fan of Downey’s work. Rather than gatekeeping the iconic role, RDJ warmly welcomed Cumberbatch into the “Sherlock Club,” with the two frequently swapping praise in the media.
The Marvel Meeting: Bringing the “Frenemy” Energy to Life
When the Marvel Cinematic Universe decided to pair Iron Man and Doctor Strange for Avengers: Infinity War, fans practically lost their minds. It was a double-layered clash of the titans: the two most arrogant, hyper-intelligent leaders of the superhero world meeting face-to-face, played by the two most famous Sherlocks on Earth.
The chemistry was instantly electric. Instead of fighting side-by-side as clean-cut allies, they played Stephen Strange and Tony Stark with a hilarious, dry, and highly competitive “frenemy” dynamic, constantly trying to out-intellect one another.
Behind the scenes, the two actors bonded beautifully, with Cumberbatch frequently praising Downey’s incredibly generous, welcoming leadership on the massive Marvel sets.
