The Lanterns panel at San Diego Comic Con unveiled several new details about HBO’s forthcoming DC series, including villains, casting and possible story developments ahead of its August release.

– Sinestro will appear, apparently imprisoned rather than serving as the immediate main antagonist.
– The Manhunters are positioned as the central threat, with one shown on a dangerous covert mission on Earth.
– Nathan Fillion’s Guy Gardner will feature in the series, though his precise role remains unclear.
– Laura Linney has joined the cast as a Guardian who advises John Stewart on being a Green Lantern.
– A final clip hinted at a possible Red Lanterns appearance, although the source of the red light was not confirmed.
