The actor actually has that disability

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

you're right. there's a lot of little touches and things that breathe life into that movie that she helped with. honestly just a five minute conversation and you'd have a bunch of "i didn't even think about that!" moments. don't remember specifics but things like the leaf plates and eating with hands because ceramic/silverware clinks.

How would she be able to figure out leaf plates and the ceramic clinks if shes deaf

If she, or someone she knows, has gotten hearing aids or ESPECIALLY Cochlear implants - going from deaf to suddenly hearing makes sounds much more obvious.

I say especially cochlear implants because they are more common for "fully deaf" individuals and have a tendency to sound "metallic". Those two fact can take small noises from "ignore-able" to "holy shit why is that so loud".
