Robert Downey Jr was almost cast as an entirely different Marvel character before he took on his most famous role as Iron Man, according to director Jon Favreau.
To mark the 15th anniversary of the first Iron Man film, which launched phase one of the MCU in 2008, Favreau sat down with Marvel Studios president Kevin Feige to discuss how Downey came to embody the role of Iron Man, aka Tony Stark.
