Heat Vision is reporting that Green Lantern might be a year away from release, but Warner Bros. is already developing a sequel.

The studio has tapped Greg Berlanti, Michael Green and Marc Guggenheim, all of whom worked on the original Lantern screenplay, to put together a treatment for the second installment.

In addition to this, the scribes are also going to write the treatment for the big screen incarnation of The Flash.

According to their deal, they would then write the screenplay for one of the two projects, though which one has presently not been decided.

Green Lantern is shooting in New Orleans. Martin Campbell is directing with Ryan Reynolds starring as the DC Comics superhero.

While development on a sequel this far out from a movie's release date is uncommon, it seems the studio likes what it has seen so far. This is also one of the first things Warner Bros. is doing under its newly configured relationship with DC.

The Flash film is going to take inspiration from Geoff Johns' (he was appointed to Chief Creative Officer of DC Entertainment in September) "recent work and will feature the Barry Allen incarnation of the character."
