The 43-year-old actress plays a brutal mother in the movie, and said it sucked a lot of her energy to the point where she couldn't wait for filming to end, reported People magazine.
"There's a lot of freedom to playing the villain, because you're doing something you would never do in real life. But it's very dark. By the end of it I couldn't wait to stop," Graham said.
The 'Boogie Nights' star would like to become a mother herself one day, but says it is not something she is obsessed by.
