“I think the script is dark and it’s dry, it’s got this amazing one-liner, glass-cutting sense of humor. Obviously the script is very cerebral. It doesn’t lose that exciting comic book aspect that people enjoyed in the first film, but it’s smart and it feels like the next installment. It doesn’t feel like a rehashing, it feels like these characters are moving forward, plotlines are moving forward. It’s deep and I think that’s why people really respond to the Marvel universe, because the films are fun and exciting and have all that flashy stuff, but there’s a gravity to them. People can expect that gravity this time around.”
Scarlett Johansson on the script for Avengers 2 (X)
“The majority of the superhero movies have not been very good. They were simply not made well. They were [about] spinning through the air and putting your hands on your hips. With the Black Widow we do something more, although of course the physicality and her image is important. To me, this character has given me a great opportunity. Joss has jumped the fence with Avengers to celebrate a female character that is not a simple ornament inside the group. He’s not interested in just selling her physical attractiveness.”
Scarlett Johannson (X)
“There’s no time for romance. We have shit to avenge.”
Scarlett Johansson 

Johansson: But I do think superhero — superheroine movies are normally really corny and bad. They’re always like, fighting in four inch heels with their [thrusting out her chest] like a two-gun salute.

Hemsworth: [Teasing] There are a few chicks in X-Men.

Johansson: [Smiles] We’ll get more.
