Robert Downey Sr. – Robert Downey Jr. (34 Years Old)
Robert Downey Sr. must have served as an inspiration to his son and it is no wonder how the Iron Man star ended up following his footsteps. He tended toward the arthouse or avant-garde genre, however. The older actor experienced a lot of success throughout the years, but he ultimately decided to retire in 2013. On the other hand, Downey Jr. must be making his father and the rest of his family proud with his huge role in the Marvel Cinematic Universe films. He has plenty of projects lined up in the future, so you can be sure his $180 million fortune will only further increase.
