Yes RDJ is Tony Stark but not to the degree that EVANNA LYNCH IS LUNA LOVEGOOD.

The ever graceful and elegant, Julie Andrews.
In 1964, Julie Andrews accepted her Best Actress Golden Globe for her role as Mary Poppins. Before filming Mary Poppins, she was considered for the role of Eliza Doolittle, before it was passed on to Audrey Hepburn. In her acceptance speech, she thanks Jack Warner for seeing Hepburn as a more “bankable” choice, thus allowing her to go on to play Mary Poppins. [x]
