8 Times MCU Cast Members Worked Together Elsewhere

Since Iron Man was released in 2008, the Marvel Cinematic Universe has grown and grown, and is now one of the biggest and most popular movie franchises in cinema history. With the initial casting of Robert Downey Jr as Tony Stark, the MCU began a pattern of incredible casting.

Now, after over ten years and more than 20 movies, this phenomenal cast has grown to ridiculous proportions. Kevin Feige and co. have made stars out of relative unknowns like Chris Hemsworth and Tom Hiddleston, and added acting powerhouses like Samuel L. Jackson and Anthony Hopkins, leaving them with a huge roster of all shapes and sizes.

With a cast as big as the MCU can boast, there is bound to be crossovers elsewhere. Actors playing characters from different corners of the MCU that you may not expect to share the screen together, that have done just that elsewhere. Whether on the big screen or in TV shows, there are plenty of times the cast have worked with each other outside the Marvel universe, either before or after they joined the MCU.

Ever since Benedict Cumberbatch joined the MCU as Doctor Strange in 2016, fans eagerly awaited the moment he and Robert Downey Jr's Tony Stark shared the screen. This eventually happened in Infinity War and later in Endgame. Two great actors, two great characters, and two great Sherlocks.

Cumberbatch has portrayed Sherlock in the BBC hit show of the same name since 2010, bringing the timeless character into the modern world. Robert Downey Jr, on the other hand, portrayed the famous detective first in Guy Ritchie's Sherlock Holmes in 2009, and Sherlock Holmes: A Game Of Shadows in 2011. These movies also featured Rachel McAdams as Irene Adler, who happens to play Benedict Cumberbatch's love interest Christine Palmer in Doctor Strange.

Not only are the two Sherlocks among the MCU cast, both of their respective Watsons are too. Martin Freeman, who compliments Cumberbatch's Holmes has appeared in both Captain America: Civil War and Black Panther as government agent Everett K. Ross. Robert Downey Jr's Watson, Jude Law, had to wait a bit longer for his MCU debut, appearing as Yon-Rogg in 2019's Captain Marvel.

As long as both Benedict Cumberbatch and Martin Freeman's characters are still alive in the MCU there is an outside chance Sherlock and Watson may meet. Unfortunately, the same cannot be said for Robert Downey Jr and Jude Law.
