Kevin Feige said the other day, he would like to have Cassie Lang, daughter of Scott Lang (Ant-Man) in to be Stature in a future movie with a new team Young Avengers or perhaps Power Pack.
Stature has the same power as Ant-Man, ability to grow and decrease in size. Cassie first appearance was in Marvel Premiere #47 (April 1979) published by Marvel Comics written by David Micheline and drawn by John Byrne. Stature first appearance was in Young Avengers#6 (May 2006) written by Allan Heinberg and drawn by Jim Cheung.
Abby Ryder Fortson played the character Cassie in Ant-Man (2015) and will be in the same role in Ant-Man and the Wasp (July 6, 2018). Abby is famous for her role in Playing It Cool (2014) and Forever My Girl (2017).
Young Avengers #6 can be bought on online for $10-$20 plus shipping.
