Over the past few days, the Green Lantern cast and crew have been filming a scene regarding an character who terrorizes a Farmer's Market (you can see the images

HERE). Yesterday, we learned that one of DC Comics'
most important cosmic entities, Krona, will be included in the film.
Today, I've learned the scene filmed yesterday was the arrival of Parallax on Earth. Regarding Krona, there's no word yet whether he is working with or against Parallax in the film; but I do have confirmation that his inclusion is pivotal to the film's plot.
