Vintage original 27x41 in. US double-sided advance one-sheet poster from the popular 2000's DC Comics superhero sci-fi action/adventure film, GREEN LANTERN, released in 2011 by Warner Bros. and directed by Martin Campbell. Reckless test pilot Hal Jordan (Ryan Reynolds) is granted an alien ring that bestows him with otherworldly powers that inducts him into an intergalactic police force, the Green Lantern Corps. The cast includes Blake Lively, Peter Sarsgaard, Mark Strong, Tim Robbins, Jay O. Sanders, and Angela Bassett. This is one of multiple styles of advance one-sheet posters, all of which were issued for display at theaters before the film was released. This one was printed double-sided for display inside of a light box, which is more desirable than the single-sided one-sheets. Unlike most of the other styles of advance one-sheets, this particular style features a close shot of Ryan Reynolds as the Green Lantern along with three other major characters from the Green Lantern Corps. Unrestored and rolled as originally issued, it is in very fine+ condition without any pinholes, tears, stains, or other flaws.
