was a life-changing experience. That's due to the extensive research we did and because I could actually realise such a big project," Downey said.

"I would still play characters like Sherlock in the future. Although, I will probably have another child and an alcohol free vineyard by then," he added. The actor enjoyed filming

Iron-Man 2

but admits it has been hard work getting in and out of his suit.

"Well the suit was a bit lighter, but not light enough for my liking. I had more self-confidence shooting the second film, but I wouldn't say we had fun. We wanted to take more time. We really looked into the storyline thoroughly to make it as good as possible," Downey Jr said. The movie, a star-studded affair has a cast that includes Gwyneth Paltrow, who reprises her role as Pepper Potts, Scarlett Johansson, who plays Natasha Romanoff and her sexy alter-ego, Russian spy Black Widow and Mickey Rourke, who plays super-villain Whiplash.
