Meet Iron Man's real superpower.
Susan Downey is the personification of the saying "behind every successful man is a great woman".
Without the missus, Robert Downey Jr, commonly known as RDJ, 49, would not be the global superstar - and highestpaid actor in Hollywood- he is now.
With a litany of drug-fuelled incidents, he was toxic property in Tinseltown. A borderline has-been. A "whatever happened to...?" trivia question.
Susan, 40, has been RDJ's guide since they got together in 2003, and this month marks another milestone for the couple - the release of The Judge, their first movie under their production company Team Downey, founded four years ago.
The emotionally charged family drama, which opens here tomorrow, sees RDJ as Hank Palmer, a slick big city lawyer who returns to his small-town home following the death of his mother.
He finds himself in a complicated situation with his estranged dad (Robert Duvall), the titular judge.
Accused of murder, he reluctantly hires Hank to defend him.
During a recent press interview, Susan said: "Robert and I had already made like six movies together. We decided that if we're going to keep doing this and enjoying ourselves, we had to do something more official."
Besides the film, RDJ and Susan have another production coming out next month - their second child. They have a two-year-old son, Exton.
For now, eyes are on how well The Judge performs. It has been suggested the drama could bring some Oscar gold for Team Downey. Here is a closer look at the woman who saved RDJ:
She's a go-getter
Born to a Chicago family in 1973, Susan Levin knew she wanted to be in the movie business.
"I had a poster in my room of all the Academy Award-winning Best Pictures," she told BuzzFeed News at the recent Toronto International Film Festival.
"Whenever there was a new one, I'd make my mum go get it for me. I loved entertaining, big Hollywood movies."
That passion guided the one-time model to graduate summa cum laude in film-making from the University Of Southern California in 1995.
She rapidly climbed the Hollywood ladder, carving a successful career as a producer with production mogul Joel Silver.
According to Box Office Mojo, the films she worked on, such as The Brave One, RockNRolla, Sherlock Holmes, The Book of Eli and Unknown, have grossed about US$2.7 billion (S$3.4 billion) worldwide.
She's straight as an arrow
Unlike her husband - the classic Hollywood child, high-school dropout and well-documented drug and alcohol abuser - Susan has not even smoked a cigarette.
Describing herself to Harper's Bazaar as "very structured, with firm boundaries", she added that she "was never a partyer".
"I used to enjoy some red wine, but now I don't do anything and I honestly didn't know anyone who had drug problems."
