Question:
Gregory Allen Kurstin (born May 14, 1969) is an American record producer, musician and songwriter. Described as "the consummate DIY writer and producer", Kurstin has been associated with releases which have cumulatively sold more than 60 million albums worldwide. He has won five Grammy Awards, including Producer of the Year (Non-Classical) in 2017 and 2018. Kurstin co-wrote, produced and played most of the instruments on the record-breaking 2015 Adele single, "Hello".
In 2004, Kurstin was introduced to singer Inara George by a mutual friend, Mike Andrews. Then producing George's solo debut, Andrews hired Kurstin as a pianist for the album. Kurstin and George clicked musically in the studio and together they formed The Bird and the Bee (stylized as "the bird and the bee"). Shortly thereafter, they were signed by Blue Note Records chairman Bruce Lundvall. Described by Entertainment Weekly as "space-age pop that cunningly combines bossa nova languidity with Beach Boys-style lushness", they have since released four albums and an EP. Kurstin was nominated for a Grammy Award for Best Engineered Album for the Bird and the Bee's 2015 release, Recreational Love. After working on tracks with artists including Peaches, All Saints, Pink, the Flaming Lips, and Kylie Minogue, Kurstin was introduced to Lily Allen. Along with other musicians, co-writers, producers and engineers, he worked on her 2006 debut, Alright, Still, which went on to achieve platinum status. For her second album It's Not Me, It's You, Allen worked exclusively with Kurstin; he co-wrote every song and played all of the instruments on the record, which he also engineered and produced. The album's first single, "The Fear", spent four weeks at number 1 in the UK, and the album hit number 5 in the US and charted in the top 10 in eight other countries. With Allen, Kurstin won three Ivor Novello Awards for his work on the double-platinum It's Not Me, It's You. Based in part on the album's success, as well as his work on a bird and the bee record, Kurstin was nominated for his first Producer of the Year Grammy in 2010. Kurstin's first commercially available collaboration with Sia was "Death by Chocolate", released on her 2008 album Some People Have Real Problems. In 2010, he produced Sia's fifth album, We Are Born. It reached number 2 in Australia and number 37 in the US. It won ARIA Music Awards for Best Pop Album and Best Independent Release.

input: In 1985, Winfrey co-starred in Steven Spielberg's The Color Purple as distraught housewife Sofia. She was nominated for an Academy Award for Best Supporting Actress for her performance. The Alice Walker novel went on to become a Broadway musical which opened in late 2005, with Winfrey credited as a producer. In October 1998, Winfrey produced and starred in the film Beloved, based on Toni Morrison's Pulitzer Prize-winning novel of the same name. To prepare for her role as Sethe, the protagonist and former slave, Winfrey experienced a 24-hour simulation of the experience of slavery, which included being tied up and blindfolded and left alone in the woods. Despite major advertising, including two episodes of her talk show dedicated solely to the film, and moderate to good critical reviews, Beloved opened to poor box-office results, losing approximately $30 million. While promoting the movie, co-star Thandie Newton described Winfrey as "a very strong technical actress and it's because she's so smart. She's acute. She's got a mind like a razor blade." In 2005, Harpo Productions released a film adaptation of Zora Neale Hurston's 1937 novel Their Eyes Were Watching God. The made-for-television film was based upon a teleplay by Suzan-Lori Parks and starred Halle Berry in the lead female role. In late 2008, Winfrey's company Harpo Films signed an exclusive output pact to develop and produce scripted series, documentaries, and movies for HBO. Oprah voiced Gussie the goose in Charlotte's Web (2006) and voiced Judge Bumbleton in Bee Movie (2007), co-starring the voices of Jerry Seinfeld and Renee Zellweger. In 2009, Winfrey provided the voice for the character of Eudora, the mother of Princess Tiana, in Disney's The Princess and the Frog and in 2010, narrated the US version of the BBC nature program Life for Discovery. In 2018, Winfrey starred as Mrs. Which in the film adaptation of Madeleine L'Engle's novel A Wrinkle in Time.

Answer this question "Which other film does he stared in?"
output: Oprah voiced Gussie the goose in Charlotte's Web (2006) and voiced Judge Bumbleton in Bee Movie (2007),

Answer the question at the end by quoting:

Sam Benjamin Harris (born April 9, 1967) is an American author, philosopher, neuroscientist, blogger, and podcast host. He is a critic of religion and proponent of the liberty to criticize religion. He is concerned with matters that touch on spirituality, morality, neuroscience, free will, and terrorism. He is described as one of the "Four Horsemen of atheism", with Richard Dawkins, Christopher Hitchens and Daniel Dennett.
Harris was born on April 9, 1967 in Los Angeles, the son of actor Berkeley Harris and TV producer Susan Harris (nee Spivak), who created The Golden Girls. His father came from a Quaker background and his mother is a secular Jew. He was raised by his mother following his parents' divorce when he was aged two. Harris has stated that his upbringing was entirely secular, and his parents rarely discussed religion, though it was always a subject that interested him. Fellow critic of religion Christopher Hitchens once referred to Harris as a "Jewish warrior against theocracy and bigotry of all stripes". While a student at Stanford University, Harris experimented with MDMA, and has written and spoken about the insights he experienced under its influence. Though his original major was in English, he became interested in philosophical questions while at Stanford University after an experience with the psychedelic drug MDMA. The experience led him to be interested in the idea that he might be able to achieve spiritual insights without the use of drugs. Leaving Stanford in his second year, a quarter after his psychedelic experience, he went to India and Nepal, where he studied meditation with Buddhist and Hindu religious teachers, including Dilgo Khyentse. Eleven years later, in 1997, he returned to Stanford, completing a B.A. degree in philosophy in 2000. Harris began writing his first book, The End of Faith, immediately after the September 11 attacks. He received a Ph.D. degree in cognitive neuroscience in 2009 from the University of California, Los Angeles, using functional magnetic resonance imaging to conduct research into the neural basis of belief, disbelief, and uncertainty. His thesis was titled "The moral landscape: How science could determine human values", and his advisor was Mark S. Cohen.

when was he born?
born on April 9, 1967
