On April 4, 2018 Marvel Studios revealed their newest batch of character posters for Avengers: Infinity War and nerd hearts everywhere rejoiced. The Russo brothers won't even screen the movie in full until the world premiere in Los Angeles. Those involved in the film has worked so hard for the past two years keeping the highest level of secrecy, so as a favor to these people, the directors request that fans at the press tours do not reveal spoilers online.
So, if you happen to be one of those people who gets to hit up a promo/press screening, or you snagged early tickets, the Russo Brothers want you to keep the secrecy efforts going just a little while longer.
Avengers: Infinity War is fast approaching, and fans from every corner of the globe can barely contain their excitement for the film that represents the culmination of a decade of Marvel movie goodness.
Good luck and happy viewing.
The Infinity Stones appeared constantly in the MCU after that moment, some of which we did not know were Infinity Stones until later.
There is also a commercial that's treating fans with a better look at the NY battle in "Avengers: Infinity War" where Iron Man (Robert Downy Jr.), Doctor Strange (Benedict Cumberbatch), Bruce Banner (Mark Ruffalo) and Wong (Benedict Wong) will be teaming up. Basically, the writing may well be on the wall for the Avengers' most valuable single character and it definitely deserves an investigation.
