Look who's moving to "Roswell."

The CW's reboot of the sci-fi romantic drama has cast five more actors for its pilot: Nathan Parsons ("The Originals," "True Blood"), Tyler Blackburn ("Pretty Little Liars"), Lily Cowles ("BrainDead"), Michael Vlamis ("New Girl"), and Heather Hemmens ("If Loving You Is Wrong").

They'll star opposite lead Jeanine Mason, the "So You Think You Can Dance" winner currently appearing on "Grey's Anatomy." The pilot is from "Originals" writer Carina Adly MacKenzie and directed by Julie Plec (the "Originals" creator).

The reboot centers on Liz (Mason), a jaded biomedical researcher and the daughter of undocumented immigrants who moves back to her hometown of Roswell, New Mexico. There, she makes the shocking discovery that her high school crush Max (Parsons), is actually an alien with powers. She tries to help Max, now a police officer, keep his identity secret but "the politics of fear and hatred threaten to expose him and destroy their deepening romance."

Cowles plays the polished and restrained Isobel, while Vlamis is the troubled Michael. Blackburn's Sgt. Alex Manes returns from the Middle East to bow to his father's expectations. And Hemmens plays Liz's free-spirited former best friend, Maria.

The project is still just in the pilot phase, but it seems highly likely that The CW will pick it up to series, especially since the network is adding original programming to Sunday nights.
