Geoff Boucher: ''Ask a young moviegoer to name a larger-than-life genius played by Robert Downey Jr. and they’ll probably name Tony Stark or Sherlock Holmes. The actor himself, however, might cite Charlie Chaplin. Downey earned his first Oscar nomination for channeling the Litttle Tramp in Chaplin (1992), which was produced and directed by Richard Attenborough, the esteemed British actor and filmmaker who today, at age 89, still presides over the Royal Academy of Dramatic Art.
The actor’s affection for Attenborough as a mentor gives him common ground with Ben Kingsley, who portrays the nefarious terrorist the Mandarin in Iron Man 3 (opening May 3). Kingsley, you’ll recall, won an Oscar for the title role in Attenborugh’s most celebrated film, Gandhi, in 1982. Here, Downey talks about that bond in the third installment of our five-part interview with the brightest silver screen star in the Marvel Universe.''
