20 Brilliantly Obscure Marvel Movie Easter Eggs You Didn't Notice

5. The Infinity Gauntlet

In Thor, during the key sequence in which the Destroyer awakens and kills two thieves in the Asgard weapons vault, in order to foreshadow its immense power and easy violence, there's a very brief flash in the background of a familiar, devastating weapon that ties Thor to The Avengers movie via a mid-credits scene. Though Thanos will not play a major role in Avengers: Age Of Ultron (unless everyone is being lead up the garden path) this Gauntlet nod was obviously a little foreshadowing for the culmination of Phase 3, that will see the arc brought to screen for Infinity Wars.
