'A Real Pain' star Jennifer Grey joined The Hollywood Reporter for a conversation at the St. Regis Deer Valley during the Sundance film festival in Park City, Utah. The actress, who is best known for her work in movies like Dirty Dancing and Ferris Bueller's Day Off, was considering a role in the story (written and directed by Jesse Eisenberg) about two cousins who join a Jewish heritage tour in Poland to reconnect with their late grandmother and visit the town that she fled before the war. Grey shares her reaction with THR after she read this script for the film.
