Robert Downey Jr, who"s Iron Man stormed the box office, had a tough time shooting for its sequel Iron Man 2. He said that shooting for the first film was an intuitive process and it was important to have things right for the second. He added that, he hopes the hard work everyone has put into the project comes across on-screen.
Downey said that he is not at all worried about the box office performance of the second film and his stress levels are at an all time high. The actor, whose last film Sherlock Holmes apart from doing good business also got positive reviews said that, he returned for the sequel because of director Jon Favreau. He added that two of them do good work together and he wouldn"t have been there if it was not for Favreau.
The first film did wonders at box office and the entire cast and crew is expecting similar fate for Iron Man 2, which releases on May 7. In addition to original cast, audiences will also get to see Scarlett Johansson, Mickey Rourke, Don Cheadle and Sam Rockwell in the Iron Man 2.
