Holmes opted to keep her prosthetic belly on while hitting up craft services, picking up a Diet Coke while taking a break from filming the movie which follows a Holocaust survivor who takes on the government in an attempt to recover artwork she believes belongs to her family.
The film, which is set in 1998, also stars Helen Mirren and Elizabeth McGovern and hits theaters sometime in 2015.
Holmes is also set to play Jonas' mother in the highly-anticipated film adaptation of The Giver, which will be released on August 15. Tom Cruise's ex-wife is also set to return to TV in an untitled ABC pilot, in which she plays a member of New York's high society.
