As part of their promotion to get as much Oscar consideration as possible for Avengers: Endgame, Disney has released the full script for the record-setting film so that members of the Academy may read through it. You can do it too if you want, but it's 149 pages, and also you unfortunately don't get a vote. 

As pointed out by Comicbook.com, this full script contains information that never actually made it to the big screen, including a reveal of a trio of additional characters that were disintegrated by the snap. Those were set to include:

Wong (Benedict Wong), Jane Foster (Natalie Portman) and Secretary Thaddeus Ross (William Hurt).

None of those three faces were included in the final film along with the faces of the more than a dozen characters who had vanished, when those who were used were shown in the sequence at the beginning of the movie where the heroes regroup after Captain Marvel returns to Earth.

As it is, all three of those characters will be back following the events of Endgame anyway, in the movies Doctor Strange in the Multiverse of Madness (2021), Thor: Love and Thunder (2021), and Black Widow (2020), respectively. 

The newly released screenplay also revealed via a scrapped title card that Captain America reunited with his long lost love, Peggy Carter, in the year 1949. That little bit of info was divulged in the final pages of the script when the then 112-year-old Steve Rogers hands down his shield to the next-in-line, Sam Wilson (Anthony Mackie). For those of you who may be really into chronological ordering and continuity, this means that Steve and Peggy's dance occurs two years after Agent Carter's second season. 

Your life is now richer.

Speaking of rich, Disney is currently trying to lobby for an Academy Awards in 14 categories for Endgame, the biggest of which include: Best Director, Best Adapted Screenplay, Best Supporting Actor, Best Supporting Actress, and Best Picture.
