Greg Berlanti, Michael Green and Marc Guggenheim—all of whom worked on the first installment—have been hired to begin writing for the second movie, according to The Hollywood Reporter
Who are these guys? Berlanti created Everwood and is an executive producer on Brothers and Sisters. Guggenheim co-created Eli Stone with Berlanti and is executive producer and co-creator of the upcoming ABC superhero drama No Ordinary Family.
Starting work on a sequel so far out from a movie's release is rare, indicating the studio's confidence that green will turn out to be gold.
