Seasoned actress Julianne Moore has got the opportunity to work with both Kristen Stewart and Robert Pattinson, who were popularly known as "Robsten" some time back. The 55-year-old actress is all praises for the "Twilight" actors saying they both are very mature and are well aware of the their work. Moore, who has worked with Kristen in the upcoming movie "Still Alice," says she knows the 24-year-old actress since she was a teenager. Kristen plays the role of Moore's daughter in the movie that tells the story of a psychology professor, played by Moore, who is battling an early onset of Alzheimer's disease.

Moore's husband director Bart Freundlich directed Kristen in the movie "Catch That Kid" when she was just 12-years-old. Freundlich told Moore at that time that he sees a star in a young Kristen. "...I can remember when he was casting it, and he's like: "This is the girl I want to work with. This girl is extraordinary. She is going to be a huge star, she's a major talent," said Moore about Kristen in a recent interview with Indiwire.com. Moore says she is amazed by Kristen's "enormous reserve of emotion." She told the website that though Kristen is "only 24 years old" but she "has a remarkable degree of maturity and compassion."

Moore has also worked with Kristen's "Twilight" franchise costar, Robert Pattinson in "Maps to the Stars." The actress says she was expecting Rob to be very quiet and reserved guy but was surprised when he started chatting with her about the movie. The actress was also impressed with Rob's knowledge about the movie. She also praised Rob for his good looks. "He has this formidable, very beautiful face. He's such a gorgeous guy," said Moore about Rob, according to entertainment.inquirer.net. Moore was all praises for the British actor and called him "friendly, truly delightful, smart and talented" actor whom she "loved right away." In the movie "Maps to the Stars," Robert plays the role of a Hollywood limo driver and aspiring actor. He has some really steamy scenes with Moore in the back of his car. Moore plays the role of a "crazy seeming actress," according to Vanity Fair.
