The Gene Siskel Film Center in Chicago has honored actor Robert Downey Jr. with a Renaissance Award.
The actor was at Chicago's at Chicago's Ritz Carlton Hotel on Saturday to accept the award.
The film center says it chose to honor the 45-year-old Downey because he is "one of the most respected and versatile actors of his generation."
In an interview following the ceremony, Downey said three of his movies are the "most representative" of his work: 'Tropic Thunder', 'Sherlock Holmes', and 'Iron Man'.
"Those three movies are the most representative of my work," he said. "I'm just glad that I didn't cheese out and phone in a performance on films that did so well."
He explained 'Iron Man' was the role he wanted the most, and spent the most time preparing for, but the role he's done the most research for is 'Chaplin'.
Downey also explained he had moved on from his struggles with drug and alcohol.
"I don't really think about it much anymore," he said. "I used to think, 'Everywhere I look, there are all of these issues. I need some dope... but having a gargantuan hangover is not a great feeling."
Downey will next be seen in 'Due Date', as a first-time dad trying to make it home in time for the birth of his baby. The film co-starring Zach Galifianakis is set for a November release.
