Robert Downey Jr.
Robert Downey Jr. started out his filming career as an adorable kid. He was just five years old when he acted in his first movie. He gained popularity and success, starring in multiple movies like Weird Science (1985), Back to School (1986), and Only You (1994). He then went through a rough period in the ’90s and early 2000s, where he had issues with substance abuse.
He definitely found the strength to bounce back, though, and began his rise to worldwide fame when he played the role of Tony Stark, a.k.a. Iron Man in Iron Man (2008). From there, there was no way but up. He played the genius, billionaire, playboy, philanthropist. His looks are the perfect embodiment of the character. RDJ exudes the rugged yet handsome looks of a confident hero.
