16-year old actor Emma Fuhrmann has been cast to play a slightly-older Cassie Lang in Marvel Studios' as-yet-untiled Avengers 4, according to The Hashtag Show. The 10-year-old Abby Ryder Fortson plays Cassie in both the original Ant-Man and the upcoming Ant-Man & The Wasp.
While her role has yet to be confirmed, Fuhrmann made this interesting tweet in mid-March that if read the right way not only alludes to her casting but her joining the Avengers team itself:

In comic books, Cassie Lang grew up to become a member of the Young Avengers (and later the Mighty Avengers) as the size-distorting Stature.
If an older, teenage Cassie Lang is indeed appearing in Avengers 4 (again, Fuhrmann is 16), it could support Newsarama's theory of our time travel "Avengers Forever" theory for the film.
Fuhrmann has previously appeared in the films Girl Followed and Lost in the Sun.
Avengers 4 is scheduled for release May 3, 2019.
