Louise Linton

Louise Hay was born in the Murrayfield area of Edinburgh, Scotland, the youngest of three children of William and Rachel Hay. Her family owns Melville Castle outside Edinburgh, where she used to spend weekends.

Linton was educated at St George's School for Girls and Fettes College. She was interested in acting from an early age; after observing students from Pepperdine University participating at the Edinburgh Festival, she vowed to her father that she would one day attend "Pepperdine and be an actress." She trained in Edinburgh with a private coach from the London Academy of Music and Dramatic Art, from which she gained honours after an exam.

Linton's mother died of breast cancer, aged 53, when Linton was 14 years old. After boarding school, Louise spent part of her gap year as a volunteer in northern Zambia, before attending university in the United States.Linton has stated that she adopted her stage surname from her grandfather, partly to protect her family and partly to avoid confusion with the author Louise Hay.

Her first role was as a guest star in CSI: NY playing Simone de Lille, a French au pair to a New York teenager played by Shailene Woodley. The episode aired in 2007.

Her first film was 2007's Lions for Lambs, directed by Robert Redford, starring Tom Cruise and Meryl Streep, in which Linton played Miss M, but her scenes were dropped from the final release. In 2008, she portrayed Katie in the Roy Lee horror film The Echo. According to the film's director, Yam Laranas, Linton was not his first pick of actress but he agreed to give her the role because her then-husband Ronald Richards paid him $200,000. Her first lead role was in the sci-fi film Scavengers. In 2016, she appeared in Cabin Fever, a remake of the 2002 film of the same name and played the lead role of Elizabeth in the thriller Intruder. In 2009 Linton appeared in the Cold Case episode "WASP" in which she played Louise Patterson, a 1940's Women Air Force Service Pilot. She also appeared in the film Crew 2 Crew. Linton was featured in the 2003 reality TV series Hopelessly Rich.

In 2009, she was honoured at the Scottish Style Awards as the country's 'Most Stylish Woman’.

Linton posed for Maxim in 2009. Maxim dubbed her "the hottest thing to come out of Scotland since microwaved haggis.”

In interviews from 2009 to 2011, Linton recounted volunteering during her 1999 gap year in what she described as "war-torn Zambia", and the night she spent "hiding in the bush as Hutu rebels attacked the village she was working in". In 2016, she self-published her memoir about her experiences in Zambia, titled In Congo's Shadow, co-authored by Wendy Holden.

Louise was blessed and fortunate enough to be raised in a Scottish castle, and to not understand the reality of some human beings with a different background.

In February 2017, Linton succeeded her fiancé, Steven Mnuchin, as the interim CEO of Dune Entertainment. Mnuchin had founded Dune in 2004 but stepped down as part of his ethics agreement to divest his business roles in preparation for his appointment as Secretary of the Treasury. Linton publicly announced her new role in early May, which immediately drew the attention of Senator Ron Wyden (D-Oregon), a member of the Senate Finance Committee. Wyden questioned whether the appointment of Linton meant Mnuchin had fully divested from the company. Although the Treasury replied that she was serving in an uncompensated capacity, Linton resigned as interim CEO later in May.

Linton is involved in The Rockshiel Trust, a Scottish legal entity, which applied to develop townhouses and apartments in the upmarket area of Murrayfield in Edinburgh close to the Hay family's Edinburgh home. The plans for 9 Kinellan Road were objected to by the local community and the plans submitted to City of Edinburgh Council in January 2019 were later withdrawn.

Linton's production company Stormchaser Films acquired Serial Daters Anonymous and completed the film’s production and post production. Linton stars opposite Sam Page. The film has not yet been released.

In 2019, Linton wrote, directed, produced, financed, and starred in the feature film Me You Madness opposite Ed Westwick in which she plays a murderous, sex-addicted hedge fund manager. The movie was released on 12 February 2021.
