4. Josh Brolin’s surprise appearance with the Infinity Gauntlet (2014)
In July of 2014, during Marvel Studios’ panel for their upcoming film Avengers: Age of Ultron, Chris Hardwick (host) asked the panel what comes next for the Avengers after Ultron. Robert Downey Jr. than grabbed the mic and said “the great thing about Marvel is they always have the next thing up their sleeve. So we’ve got Thanos.” Just then Josh Brolin appeared on stage with a mock Infinity Gauntlet. As you can hear in the video below, the 6,000 plus in attendance loved it.
