'Iron Man' wants to voice Mark Zuckerberg's virtual assistant

If you're building Iron Man's virtual assistant, who better to help than Iron Man himself? Facebook CEO Mark Zuckerberg, who's been working on the virtual assistant as part of his New Year's resolution from earlier this year, posted on his social network Thursday that he was looking for someone to voice his latest creation. Robert Downey Jr., who famously plays Iron Man in the Marvel Studios franchise, jumped at the chance to contribute. In a response to the Facebook founder, Downey Jr. said he'd "do it in a heartbeat" if the fees go to Paul Bettany, the voice of Iron Man's virtual assistant Jarvis in the hit movies. Not forgoing a chance to further publicize the Marvel universe, Downey Jr. continued saying that Bettany would then have to donate the funds to a charity "of Cumberbatch's choosing." Benedict Cumberbatch plays Doctor Stephen Strange, the latest Marvel superhero set to hit theaters in his own blockbuster film next month, Doctor Strange.
