Scarlett Johansson clarified that this doesn’t mean an actor shouldn’t be “physically comfortable with the stunt work and choreography,” saying that in some ways, it should be “second nature.” However, Johansson recalled that when she shot Iron Man 2, that was at a time when actors were doing a lot more of their stunts. She specifically mentioned how the hallway scene where Black Widow fought off the security team at Justin Hammer’s factory was “really complicated,” with the choreography being “less fine tuned” for the actors.
