Drafts of The Flash and the Green Lantern sequel are expected to be delivered to Warner Bros. by Christmas, Deadline reports.

Written by Greg Berlanti, Michael Green and Marc Guggenheim, The Flash reportedly will use Geoff Johns’ take on the character as a model and fuse sci-fi elements with a darker crime component. Although no director has been announced, Deadline says it's unlikely to be Berlanti, whose comedy Life as We Know It opened at No. 2 over the weekend.

The same writing team is also working "round the clock" on the script to the Green Lantern sequel, even as director Martin Campbell edits the first film (which Deadline's Nikki Finke says she hears is shaping up to be "jaw-dropping").

Starring Ryan Reynolds, Blake Lively, Mark Strong and Peter Sarsgaard, Green Lantern is set to open on June 17, 2011.
