Newly promoted Chief Creative Officer of DC Entertainment Geoff Johns has confirmed via his Twitter account, that the upcoming Green Lantern film has found its Sinestro in Mark Strong.

According to his first tweet “Ryan IS Hal. And Mark Strong is going to be a brilliant Sinestro” and according to his second, “Kilowog, the Guardians, Oa”¦all breathtaking. The age of Green Lantern is upon us!!”

Previously, Strong had just been “in talks” back in January to portray IGN‘s 15th Greatest Comic Book Villain of All Time (read Jackie Earle Haley NOT Sinestro In “˜Green Lantern’ But Mark Strong Might Be!).

Strong joins Ryan Reynolds, Tim Robbins, Blake Lively, and Peter Sarsgaard in the Martin Campbell-directed Green Lantern, which is scheduled to be released in theaters June 17, 2011.
