Catherine Ann Bosworth was born January 2, 1983 and is an American actress and model. Following minor roles in the films The Horse Whisperer (1998) and Remember the Titans (2000), she rose to prominence with her role as a teenage surfer in the box-office hit Blue Crush (2002).

She also had roles in independent films, she portrayed Lois Lane in Superman Returns (2006), and had roles in 21 (2008), Straw Dogs (2011), And While We Were Here (2012), and Still Alice (2014).

She was born in Los Angeles, California, and then raised in San Francisco, California, the only child of Patricia (née Potter), a homemaker, and Harold Bosworth, a former executive for Talbots. She was born with heterochromia iridum, and has a hazel right eye and a blue left eye. When Bosworth was six years old, her family relocated from San Francisco to various parts of the country due to her father’s job. She was raised mainly on the East Coast, spending the rest of her youth in Massachusetts and Connecticut.

Bosworth developed an interest in competitive horse racing, and by the age of fourteen, she was a champion equestrian. She graduated from Cohasset High School, in Cohasset, Massachusetts, in 2001. 

Bosworth’s first film role came after an open casting call in New York for the supporting part of Judith in the 1998 film, The Horse Whisperer. The film’s producers needed someone who was already an experienced horse rider, leading to Bosworth’s successful audition for the role. In 2001, Bosworth moved to Los Angeles in hopes of obtaining easier access to auditions and better film parts.

In late 2018, Bosworth and her husband, Michael Polish, debuted the film that they privately funded called Nona. The film focuses on the issues of human trafficking. She works closely with CAST, the Coalition to Abolish Slavery and Trafficking.

Bosworth was accepted to Princeton University in late 2000, but because of continual deferral of her attendance, her acceptance was revoked. She is a member of the Appalachia Service Project.
