HisSherlock Holmesduology is incredibly appreciated, and it all started here.

His performance in this flick contrasted with his as Tony Stark in the best ways.

Downey Jr.’s dynamic with his co-stars,Mark RuffaloandJake Gyllenhaal, is amazing.

He knows how to play off of others and really gets to show it off here.

It was a true mark of the impact that the character and actor had on Hollywood and viewers everywhere.
