“Small Great Things” centers on a labor/delivery nurse who takes care of newborns at a Connecticut hospital who’s ordered not touch the baby of a white supremacist couple. When the baby dies in her care, she’s then taken to court by the couple.
Roberts has been nominated for four Academy Awards and won Best Actress in 2001 for “Erin Brockovich.” Davis scored her third Oscar nomination for “Fences” in reprising her Tony-award portrayal for the film.
Picoult wrote “My Sister’s Keeper,” which was adapted into a movie directed by Nick Cassavettes in 2009. Platt and Amblin teamed on Tom Hanks’ 2015 thriller “Bridge of Spies.”
Platt’s producing credits include “Legally Blonde,” “Rachel Getting Married” and “2 Guns.” He’s received back-to-back Best Picture Oscar nominations for “Bridge of Spies” and “La La Land.”
