Johansson loves the 'Black Widow'
The 27-year-old actress is reprising her role in the forthcoming superhero movie, after starring as the character in 2010 movie 'Iron Man 2'.
She said she was well prepared for wearing the costume.
"I love her. So putting on the suit is like, 'Ah, the old familiar friend'. You have all this history to fall back on. She's all business. She's just a machine. You can't get her down," femalefirst quoted the actress as saying.
