After being released, Downey joined the cast of the TV show Ally McBeal, and he was later won a Golden Globe for his role as Larry Paul. However, Downey was again arrested for drug possession in 2000 and 2001 , and he was fired from Ally McBeal and lost out on some film roles. In fact, the actor couldn't get insured to make a movie until 2003's The Singing Detective.

Downey has been sober ever since then, and he later starred in Kiss Kiss Bang Bang, Zodiac , and Tropic Thunder, which got him nominated for an Academy Award for Best Supporting Actor.

But of course, Downey's major win came with Iron Man. In 2005, Downey landed the role of a lifetime as Tony Stark, the man behind the Iron Man suit. The film wouldn't debut until 2008, but that gave Downey enough time to make the film and rake in a reported $10 million for the role.

Just a few short years later, Downey was named Forbes' world's highest paid actor , bringing in $80 million in 2015 and it was all thanks to the MCU. Though he's dropped down in the rankings since then, Downey was still on the highest-paid list in 2018, sitting pretty at number 20 .

In 2019, Downey earned a stunning $75 million for his role in Avengers: Endgame. Initially, Marvel paid Downey Jr. $20 million up front, but after the movie premiered, he took home an additional $55 million on the backend. Endgame went on to make over $2.5 billion worldwide . He's reportedly being paid $20 million for 2020's Dolitte, and he may make more money after the movie debuts as well.

Downey has certainly made a major comeback, and brought all the money in the world with him.
