Ellie in The Last Of Us
Not sure if this has been mentioned previously, but I think Mackenzie could be a great choice to play Ellie in The Last Of Us movie.
The movie is in early development now. If filming get's underway sometime next year, she would be the right age.
She has great range for a young actress (Interstellar) and I think she has the ability to convey not only Ellie's vulnerability and emotion, but also her strength and independence.
Mackenzie alongside the likes of Hugh Jackman or Josh Brolin as Joel would make a great leading pair in my opinion.
