Avengers 2 will reveal Black Widow's sad past, says Scarlett Johansson

Scarlett Johansson has revealed that Black Widow's sad past will be revealed in the upcoming movie Avengers: Age of Ultron.

In an interview with W magazine, she says, "In the sequel, you learn more about the sadness in her past."

Talking about how she landed the role, Johansson said, "People were surprised that I wanted to play a comic book heroine. But I loved Iron Man, and I met with Marvel to see what was possible. I had done my research, and the Black Widow character resonated with me. She is dark and has faced death so many times that she has a deep perspective on the value of life."

Avengers: Age of Ultron is set for release on May 1 in the US.
