In the latest piece of marketing for Avengers: Doomsday, Marvel has begun streaming the Doomsday Clock. The YouTube video features the now-iconic Avengers A, backlit by something reminiscent of green stained glass — green, of course, being one of the primary colors of the film’s antagonist, Doctor Doom. The only text on the screen reads “Doomsday is Coming.” Accompanied by the sound of a ticking clock, a timer counts down the months, days, hours, minutes, and seconds until the film’s December release.
