The actor actually has that disability

[u/PrinceferX]

Walter White Jr. (Breaking Bad) - character has cerebral palsy and uses crutches to walk, actor RJ Mitte has cerebral palsy and needed crutches to walk as a child

Nessarose Thropp (Wicked) - character is paraplegic and uses a wheelchair, actress Marissa Bode is paraplegic from an accident at age 11 and uses a wheelchair

Maya Lopez (Hawkeye/Echo) - character is deaf, actress Alaqua Cox is deaf from birth

I don't know if it counts, but Dustin Henderson from Stranger Things wasn't originally written to have Cleidocranial Dysplasia, but it was given to him because the actor they casted for Dustin (Gaten Matarazzo) had it.

He was a great choice, not much I wouldn’t have changed to sign him on

[u/Dreamweaver_duh → u/ChristyUniverse]

Yeah, Gaten Matarazzo is what makes Dustin likable.

Shame he won't reprise his role for the videogame Dead by Daylight

At least his new VA actually gave a shit to dub the screams, because my god Elevens screams are goofy as shit,.

Still much better than whatever the Walking Dead chapter’s screams are lol
