For this discussion I'm going to use "special needs" to refer to people with an array of physical and mental problems. There is no term I'm wholly comfortable with that collects things so ranging. "Disability" doesn't even cover it for me, and is sometimes more uncomfortable. But know that preference of terminology changes from person to person. This is always easier talking person-to-person, where you can tailor to what makes individuals comfortable.
You probably don't know Nathan Jones. He was a professional wrestler who quit because, at 6'11" (2.1 meters), travel became incredibly painful. He didn't fit in an airplane seat or on any motel mattress, and good luck driving a rental car from town to town with legs that long. He quit WWE in 2003 and went into film. To date, I don't think I've seen him in a film that acknowledged his size could be a problem in life. He tends to play villains, because it's easier for average people to see giants as powerful and dangerous.
He plays Rictus Erectus in Max Mad: Fury Road. He lumbers through the movie with very few lines. When he speaks, it sounds like the character has a learning disorder. That's typical of giant villains.
Since he has no individual agency, always acting in obeisance to his murderous father (Immortan Joe), his only further characterization is a breathing apparatus strapped to his back and plugged to his nose. He chases heroes, overpowering any he gets his hands on because Dad told him to. Late in the movie, a hero finally manages to stab Jones's breathing machine. Jones crumples, possibly suffocating, and my whole theater laughed.
I mean, the whole theater laughed except me. But my lungs are probably what'll kill me, so I'm biased.
