Paramount Pictures has just released several new pictures from Robert Downey Jr.-starring film "Iron Man 2". After releasing a poster which gives the first look at War Machine, the studio has shared four stills which feature some previously-exposed characters, like Tony Stark, Black Widow, and Ivan Vanko.

In one image, master engineer Stark is seen working with an electronic stuff. In another picture, he is exposed with his robotic buddy. Meanwhile, one particular photo shows Black Widow, the alter ego of Natasha Romanoff, in her tight costume. The last still additionally features Vanko standing in front of a wall which is full of clippings.

Tony Stark, Black Widow/Natasha Romanoff, and Ivan Vanko/Whiplash will be portrayed by Robert Downey Jr., Scarlett Johansson, and Mickey Rourke respectively. Meanwhile, Gwyneth Paltrow and Samuel L. Jackson will reprise their roles as Pepper Potts and Nick Fury in this "Iron Man" sequel. Joining them in the cast ensemble is Don Cheadle who replaces Terrence Howard as Col James 'Rhodey' Rhodes/War Machine.

As of late, director Jon Favreau claimed the follow-up to the 2008 film has begun to take on its final look as digital animated shots started to come in. Later, via his Twitter page, the helmer also hinted that the first trailer may arrive in December, when another Downey Jr.'s film, "Sherlock Holmes", hits U.S. theaters. Penned by Justin Theroux, "Iron Man 2" is slated to be released in the U.S. on May 7, 2010.
