Wanting to impress from minute one, Scarlett Johansson arrived already glamoured up for the promo spot, which also included Robert Downey Jr, Chris Hemsworth and Paul Rudd.

Johansson, who plays Black Widow, looked every bit the movie star A-lister in an amazing black mini dress that popped with its array of sparkling silver adornments on the chest portion and straps.

For an added touch of style the adornments were also added as a top lining for the number’s two pockets along her hips.

She paired it perfectly with a pair of black stiletto-heeled boots that had matching silver adornments around the shoe.

Keeping with the mini skirt vibe, the 34-year old star styled her blonde tresses in a pseudo 1960s look, back off her face with a left part and ponytail with some added height and volume.

Still sporting the results of his Thor-physique, Hemsworth arrived at the venue to the roar of screaming fans.
