Robert Downey Jr.’s oldest son almost looks like he could be his dad’s brother—you know, minus the beard and long hair.
Like his dad, Indio also decided to go into the entertainment business. In 2005, Indio appeared in his father’s film “Kiss Kiss Bang Bang,” and he’s also dabbled in the music industry as a performer in several bands.
Dennis Quaid & Jack Quaid
Once upon a time, Dennis Quaid and Meg Ryan were married, and though their marriage failed, one good thing did come of it; their son, Jack. Though papa Quaid's more substantial roles happened later in life, by 27, he had a pretty impressive résumé.
Jack decided to venture into acting as well, and has appeared in films like "The Hunger Games" and was most recently a star in the critically acclaimed show "The Boys."
John Ritter & Jason Ritter
This million-watt smile isn't the only thing John Ritter passed on to his son, Jason. Papa Ritter is most known for his role in the '70s sitcom "Three's Company," which he started acting in when he was only 28.
His son, Jason, turned to acting just like his father and has been in several television shows and movies by his late 20s. Losing John was hard for fans everywhere, but lucky for us, whenever we miss the late actor, we look at Jason!
Jackie Chan & Jaycee Chan
Jaycee Chan released his first Mandarin CD album in Hong Kong and later went to Taiwan to continue his music career.
Much like his dad, Jackie Chan, Jaycee established himself in Asia and became a flourishing musician before he broke into the Western industry.
Gary Busey & Jake Busey
Gary Busey had an incredible career back in the 70s and 80s, especially when he garnered acclaim for his role in "The Buddy Holly Story."
His son, Jake Busey, has carried on in the same style; he starred in films like "Starship Troopers," "Identity," and, most recently, the popular Netflix series "Stranger Things."
