LAS VEGAS -- At the age of 24, Jennifer Lawrence has starred in several blockbuster films, has an estimated $30 million net worth and earned herself an Oscar, but she hasn’t let fame go to her head according to “Mockingjay” director Francis Lawrence. During a press conference at CinemaCon, the official convention of the National Association of Theatre Owners, in Las Vegas Thursday, Lawrence dished about the actor’s attitude and what’s in store for the final “Hunger Games" film.

“I don’t think she’s really changed,” Lawrence, 44, dished of the franchise actress. “I’ve been working on these films for 3 1/2 years now and she's really wonderful. She’s an extremely talented person and very warm and fun to be around. Very down to earth, very silly. She’s exactly the same now, so, she’s fantastic.”

Lawrence, who attended CinemaCon to accept his Director of the Year award at the convention’s Big Screen Achievement Awards at Casears Palace Thursday night, also revealed what’s in store for the fourth and final “Hunger Games” film, “Mockingjay - Part 2.” “Fans can finally see the conclusion of the series,” he coyly responded when asked about what is to come in the feature. “This one finally closes the story out,” he added. “This is where we see Katniss (Lawrence) reignite and she goes to the Capitol. She goes to war.”

While the filmmaker wasn’t forward about dishing “Mockingjay - Part 2” spoilers, he did reveal that he tried to use reality in place of digital effects as much as possible. “A lot of the things you’re going to see in ‘Mockingjay - Part 2,’ a lot of the environments were real,” he said, sharing that the cast shot overseas in Berlin and Paris. “We found some fantastic architecture… I try to find as much of a real environment as possible. It always helps the actor and helps them sort of connect to what’s happening.”

While the “Hunger Games” series is quickly coming to a close, Lawrence said he has thoroughly enjoyed working on the franchise. “It’s been really gratifying to be part of these stories. It’s not often that you get to be a part of something that has real meaning and real relevance and real themes and ideas that so many people flock to see,” he said. “Doing these last two movies, these are the stories that sort of bring all of the themes and ideas together and it’s where the stories all pay off, so it’s been a real joy.”

Lawrence said there is one more scene left to shoot for “The Hunger Games: Mockingjay - Part 2," as well as some digital and sound effect tweaking that needs to occur, before it's complete. The film debuts in theaters November 20.
