Questions began to be asked regarding the filming schedule of Avengers: Age of Ultron when it was announced that Scarlet Johansson was expecting a child. The actress is due sometime around August but measures are already in place to make sure it doesn't show. As the Mirror reports:
the actress will be wearing a high-tech suit with a green band around her waist which will allow the special effects team to remove any signs of her pregnancy.
Marvel studio head Kevin Feige confirmed the pregnancy in an interview last month and had this to say on the matter:
Well my first reaction was I was very happy for her and very excited for her. My second reaction was we've got to move some pieces on the chess board around schedule-wise. But we didn't change the script at all, which is sort of the most important things for us in terms of the storyline
So sounds like everything will move forward as planned. It really is incredible what they can do these days.
The Avengers: Age of Ultron hit theatres on May 1st, 2015
