Greg Berlanti’s empire continues to expand: Scribe is developing a sci-fi project with Rene Echevarria for ABC.

Berlanti and Echevarria are behind “The Return,” which they’re developing for the Alphabet net through ABC Studios (where Berlanti is based via a megabucks overall deal).

Project revolves around the impact on the world — including the White House — when aliens land.

Echevarria arrives with full-fledged sci-fi chops, having come from the world of “Star Trek” and exec produced “The 4400” and “Dark Angel.” His other credits include “Medium” and “Now and Again.”

Berlanti is behind ABC’s “Dirty Sexy Money,” “Eli Stone” and “Brothers & Sisters.”

Both Berlanti and Echevarria are on board as exec producers on “The Return.”
