Robert Downey Jr appears on the cover of US magazine, Fortune. The 48-year-old star - the highest paid actor in Hollywood thanks to the success of the 'Iron Man' movie franchise - admits he is sometimes baffled about the future of Hollywood. "I don't know that anyone can accurately say where any industry is going at any time," he tells the latest issue of the publication, on newsstands now. "If you'd said 10 years ago that Matthew McConaughey would be the most interesting actor of 2013 or that someone like me would be at the top of the heap for box-office genre movies - I think neither he nor I would have believed it."
