While speaking to Vanity Fair, the 80-year-old icon, who is best known for her role in Terms of Endearment, said that a mutual acquaintance organised a catch up with The Hunger Games star so she could mentor her.
"I was very impressed with how real she was and still so tied to her real life and her upbringing and her boyfriend of years," MacLaine told the magazine.
"[My advice] was mostly stuff about knowing who you are. 'Find your identity because you are going to be in for a rough ride if you don’t.'"
The Oscar winner also went onto talk about the new films and stars in Hollywood. She said before a screening of the hit film Gone Girl there were several previews that "could all have been for the same film."
"Crashes and violence and explosions and all of that stuff. And that is not how I would like to define Hollywood," she said.
"My age group, from 50 on let's say, is under-served. And it's not fair," MacLaine said. "What, like I'm going to go see Spiderman 16? Now maybe I would go see Interstellar... Because for me, that is all real. That is not unusual fantasy."
The actress is starring in the romance film, Elsa & Fred, alongside Christopher Plummer, which is out later this month.
