While Avengers Infinity War and Avengers 4 focuses on Thanos gathering the Infinity Stones for his Infinity Gauntlet – a metallic glove – it’s unlikely the snap has anything to do with the film’s plot. The Russo Brothers are known for teasing the highly secretive Disney-owned movie with pictures of random objects. Last month Joe Russo gave an update on when Marvel fans could expect the highly anticipated first trailer. He said: “You know, all I can say is that when the footage comes out we want it to be exactly right.”
