Jesse Eisenberg was going to play the lead in the film he wrote and directed surrounding the Majdanek concentration camp in present-day Poland, but says both his sister and wife agreed after reading the first 20 pages of the script that it HAD to be Succession's , Kieran Culkin.
A Real Pain explores the generational trauma of a family's history when they visit the camp.
The film also stars Dirty Dancing' s Jennifer Grey and White Lotus star Will Sharpe.
Eisenberg says he hopes people find humor in the comedy/drama and they realize what actually happened on this hallowed ground.
Emma Stone produced the film.
