Even though he’s had many roles where he sang, I’m surprised that Robert Downey Jr is an amazing singer, and not just an actor.
After his earlier drug-related problems that eventually led to arrests, rehab visits and incarcerations, (and his firing from Ally McBeal in ’97), he began rebuilding his career clean and sober.
Then, in 2004, under the Sony Classics label, his album “The Futurist” debuted his music career. Since that time, he’s focused mainly on acting, however he’s been known to appear on stage a few times with some very big names.
The video below is one that made the rounds on the internet of him singing “Driven to Tears” with Sting.
