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 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.
