Of course, the Avengers 4 title was just one of the ways the back-to-back production of Avengers: Infinity War and Avengers 4 was shrouded in secrecy.
With Infinity War less than two weeks away, it won’t be much longer until we learn what Olsen and her MCU costars were up to during the first half of 2017, but we’ll still have another year to go until the proverbial curtain is pulled back on what they shot for Avengers 4 in the latter six months.
As Elizabeth Olsen also mentioned during her conversation with Digital Spy, the actors had two options when it came to the script: read the full script on an iPad in a locked private room (though as Olsen and Vision actor Paul Bettany noted, that full script also contained some lies), or just receive the pages pertaining to their character and have someone orally explain what happens in the rest of the movie.
