Robert Downey Jr. in Robert Downey Sr.’s 1970 film “Pound.”

Like father, like son: Indio Downey, Robert Downey Jr.’s son, was arrested on drug charges on Sunday, the Los Angeles Times reported.

Or perhaps it’s like grandfather, like grandson.

A 1996 People story, “Hitting Bottom,” detailed Downey Jr.’s introduction to drugs courtesy of his father Robert Downey Sr.:

 In a 1988 interview for The New Breed, a book on young actors…Downey claimed his father had introduced him to drugs (marijuana, says a female friend of the actor’s) in New York City before he was a teenager. As director of such irreverent comedies as Putney SwopeGreaser’s Palace and Pound (in which 5-year-old Robert played a puppy), Downey Sr. was a force in the counterculture of the late ’60s and early ’70s. In his family, said Downey Jr., ‘there was always a lot of pot and coke around.’ Drugs became an emotional bond. ‘When my dad and I would do drugs together,’ explained Downey, ‘it was like him trying to express his love for me in the only way he knew how.’ Eventually, Downey saw no reason not to ‘spend every night out getting drunk … making a thousand phone calls in pursuit of drugs,’ he said. 

No one alleges that Downey Jr., who got sober about a decade ago, made the same introduction for Indio Downey, a 20-year-old actor and musician.

But in a statement, Downey Jr. acknowledged the burden of history.

“Unfortunately there’s a genetic component to addiction and Indio has likely inherited it,” Downey Jr. said. “Also, there is a lot of family support and understanding, and we’re all determined to rally behind him and help him become the man he’s capable of being.”

Police said Indio Downey was “apparently using” a pipe to smoke cocaine. He was released on bail.

And here he is in his father’s 2005 film “Kiss Kiss Bang Bang”:

And here’s a 2008 interview with Robert Downey Sr. Choice quote: “We were all too drunk” to know the difference between John F. Kennedy and Richard Nixon in 1960.
