Downey gave an interview to director Todd Phillips, saying three of his movies are the "most representative" of his work, "Tropic Thunder," "Sherlock Holmes" and "Iron Man." He won a Golden Globe for "Sherlock Holmes."
The actor also says he's moved on from drug and alcohol abuse. Downey is to star in the Phillips-directed movie "Due Date" as a first-time dad trying to make it home in time for the birth of his baby.
