"The American Cinematheque is extremely pleased to honor Robert Downey, Jr. .as the 25th recipient of the American Cinematheque award at our celebration this year," American Cinematheque Board chairman Rick Nicita said in a statement Thursday. "The pleasure that we receive from his charismatic and nuanced performances is matched only by the respect that he has earned for his personal and professional journey. The wide range of his talent has kept us enthralled in movies from a biopic like Chaplin to outrageous comedies like Tropic Thunder to franchises like Sherlock Holmes and, of course, Iron Man. While we have been enjoying him for years, it seems that he's just getting started all over again. The Cinematheque is thrilled to mark this milestone in the flourishing career of Robert Downey, Jr."
