The Wikipedia says that, according to the actress, Dr. Poison’s disfigurement is a result of testing her poisons deliberately on herself. This would have been a great thing to see discussed onscreen.
That is definitely something that should not have been left on the page! Even in passing, it tells you a lot about the character: what she values, what she's willing to risk, what she views as important about herself and her relationship to her work; if nothing else, it absolutely kills even the implication that she embarked on her course of supervillainy in consequence of her disability, rather than incurring it willingly along the way—which would become a lot more neutral in a film in which the heroes had also willingly taken damage for their countries.
