Scarlett Johansson recently revealed the biggest challenge she faced while filming Iron Man 2. The actor, who first portrayed Black Widow in the Marvel Cinematic Universe (MCU) over a decade ago, stated that her main obstacle was preparing for serious stunt work for the first time. At the time, Johansson was in her early 20s and had never stepped foot in a gym. She had to make a massive lifestyle change and had to be prepared for everything due to the lack of efficiency in action scenes during the early days of the MCU. However, her dedication and training paid off, as Black Widow went from being a side character in Iron Man 2 to a fan-favorite in one of the biggest franchises in the world.
Johansson's return to the MCU in a producing capacity may present new challenges for her.
