Dominic Monaghan is confirmed for Flash Forward. His character is named Simon.
But that's not all we know about him. Producer Marc Guggenheim revealed a great deal more about Monaghan's role in an interview with E! News this week. He said:
"Simon is the smartest man in the world, and he definitely knows it. He's mysterious, but not just for story reasons. He's a mysterious kind of person. He's someone that's so intelligent that he has a difficult time interfacing with people on a human level, because he's just so much smarter than them. He's an enigmatic figure whom I hope you'll want to get to know over the course of the first season."
Flash Forward premieres on ABC on Thursday, September 24.
