Fan Casting Sinestro in Greg Berlanti's Green Lantern

The most feared and respected member of the Green Lantern Corps, Sinestro is Hal's imposing mentor on Oa. A fierce warrior who believes order must be enforced through power, Sinestro harbors a growing ambition to wield fear as a weapon. His grief over Abin Sur's death and his disdain for Hal's recklessness mask a darker truth—Sinestro believes the Guardians' methods are failing, and he is willing to break every law to prove it.
