Routh spoke privately about Superman after a news conference in Pasadena, Calif., where he was promoting his involvement with NBC's upcoming horror anthology series Fear Itself, kicking off June 5.
"Bryan keeps me up [to date] with what's going on, and I think he'll get a script together later in the year, and we'll begin filming early next year," Routh said.
The actor joked about wanting to be able to hit more villains in the sequel and added that he has stayed in shape, albeit in a less-regimented workout routine. "I'm ready to get back into the swing of it, though," he said.
Routh added that he is excited about the recent release of a small independent film Lie to Me, which co-stars his real-life wife, Courtney Ford, and tells the story of a couple in an open relationship.
In Fear Itself, Routh stars in a segment called "Community," directed by American Psycho helmer Mary Harron, about a young couple who move into a rigid neighborhood.
