DuPont's stock price dropped by 7.15 points from 72.18 to 65.03 the week this movie was released on 12th November.
Bucky Bailey is mentioned as a case study example of surviving victims several times in the film and his picture as a baby is held up to show the then DuPont CEO. The real life Bucky appears towards the end of the film in the gas station scene, thankfully looking well considering the circumstances surrounding his health.
Actual trial lawyer Rob Bilott and wife Sarah can be briefly glimpsed at the Ohio Chemical Alliance Annual Dinner right after Mark Ruffalo (as Bilott) and Anne Hathaway (Sarah Bilott) enter the crowded room (32:30).
The production name for the film was "Dry Run" which is the name of a place important in the story.
