Jennifer Shrader Lawrence (born August 15, 1990) is an American film and television actress. She had lead roles in TBS's The Bill Engvall Show and in the independent films The Burning Plain and Winter's Bone, for which she received nominations for the Academy Award, Golden Globe Award, Satellite Award, and the Screen Actors Guild Award. At age 20, she was the second youngest actress ever to be nominated for the Academy Award for Best Actress. She is also known for playing Mystique in X-Men: First Class. In 2012, Lawrence achieved wider recognition starring as the heroine Katniss Everdeen in The Hunger Games, an adaptation of Suzanne Collins' best-selling novel of the same name. Her performance in the film garnered her notable critical praise and marked her as the highest grossing action heroine of all time. Lawrence's performances thus far have prompted Rolling Stone to define her as "the most talented young actress in America."

Lawrence was born and raised in Louisville, Kentucky, and has two older brothers. Her parents are Karen (née Koch), who runs a children's camp, and Gary Lawrence, who once owned a concrete construction firm, Lawrence & Associates. She acted in local theater and, by the age of 14, had decided to pursue an acting career, persuading her parents to take her to New York City to find a talent agent. Prior to finding success in Hollywood, Lawrence attended Kammerer Middle School. She graduated from high school two years early with a 3.9 average in order to begin a career in acting. While growing up and in between acting, Lawrence served as an assistant nurse at the children's summer day camp that her mother ran.

Rebecca Alie Romijn ( /roʊˈmeɪn/ roh-MAYN; Dutch: [roːˈmɛin], born November 6, 1972, formerly Romijn-Stamos) is an American actress and former fashion model. She is best known for her role as Mystique in the X-Men films, and for her recurring role as Alexis Meade on the television series Ugly Betty.

Romijn was born in Berkeley, California, United States. Her mother, Elizabeth (née Kuizenga), is a Community College teacher of English as a Second Language and textbook author, and her father, Jaap Romijn, is a custom furniture maker. Her father is a native of Barneveld, the Netherlands, and her mother is an American of half Dutch descent; she met Romijn's father while staying in the Netherlands on a teen-age exchange program. Romijn's maternal grandfather, Dr. Henry Bernard Kuizenga, was a Presbyterian minister and seminary professor. When questioned about always being glamourous and beautiful on the Ellen Show, Romijn revealed that as a child in her early teens she was in fact an insecure 'drama geek', and as a result of her growth spurt she suffered from scoliosis and was constantly in pain. Many sources say that she was once nicknamed the "Jolly Blonde Giant" because of her 5 feet 11 inches (1.80 m) height, but she has admitted to making that up "for a laugh". While studying music (voice) at the University of California, Santa Cruz, she became involved with fashion modeling and eventually moved to Paris for more than two years.
