Longtime fans of Marvel Comics would have found the climax of Avengers: Infinity War very familiar. In Jim Starlin's 1991 Infinity Gauntlet storyline, we see Thanos in full command of the Infinity Stones and eager to impress the personification of Death. He does so by snapping his fingers and... well, if you've seen the film you know where this one is going. But despite the Russo brothers heavily cribbing from Starlin, there's one aspect that's curiously absent: Adam Warlock.
