Nick Moorcroft (born 22 December 1978) is a British screenwriter, director, and producer.

Moorcroft was born in 1978 in Chelmsford, Essex. He was expelled from school and diagnosed with ADHD at a young age, as well as being arrested multiple times. At a court ordered attendance centre, he discovered acting. He was offered a place at one of the country's leading drama schools - Webber Douglas Academy of Dramatic Art - when he was 18 after his mother encouraged him to audition. Unable to afford the tuition fees, he won an Essex County Council Scholarship and went on to study at the prestigious acting academy in South Kensington, London, which he left after one term in December 1997 before producing and acting in a fringe theatre production in November 1998 called The Gary Oldman Fanclub at The Man in The Moon on Kings Road. The play was directed by award-winning playwright and screenwriter Barrie Keeffe and written by Jonathan Stratford. Keeffe became a creative mentor to Moorcroft and encouraged him to give up acting and focus on writing full time which led to him embarking on a career as a screenwriter, producer and director.

In 2004 he sold his first spec script to Barnaby Thompson's Fragile Films. The period comedy, called Burke & Hare, is about two Irish serial killers who sold the corpses of their 17 victims to the Edinburgh Medical College for dissection. In Variety, an entertainment industry newspaper, the article "The 'Brit List' circulates British film community" by film journalist Adam Dawtrey, reported that the screenplay was included on the Brit List: 2007, which lists the most liked and recommended unproduced screenplays in the UK and Ireland.

In 2006 Moorcroft wrote the screenplay for St Trinian's, a film based on the cartoons by British cartoonist, Ronald Searle, for Ealing Studios. It was reported in Screen International that the schoolgirl comedy, based on the cartoons by Ronald Searle, had a budget of $13m (£6.5m) and took $26m (£13m) at the UK box office alone, making it the then third most successful independent British film, behind Four Weddings and a Funeral and Trainspotting.

Moorcroft co-wrote the 2009 sequel, St Trinian's: The Legend of Fritton's Gold with Piers Ashworth. It opened at No. 2 in the UK just behind Avatar with debut week end box office figures of £1,586,832.[4] As of 10 February 2010, the film has grossed a total of £7,019,714, which is lower than the first installment's £12,280,529. It was the fourth biggest hit of the Christmas season behind Alvin and the Chipmunks: The Squeakquel, Sherlock Holmes, and Avatar.

Burke & Hare started shooting on 28 January 2010. The film was directed by American filmmaker John Landis and starred Simon Pegg and Andy Serkis as the murderous duo. Filming took place around Edinburgh with some scenes also being shot in Stirling and London and Ealing Studios. It was released on 29 October 2010.

On 31 April 2010, Barnaby Thompson, head of Ealing Studios and Fragile Films, announced to the British press that screenwriters Nick Moorcroft and Piers Ashworth were to write a film comedy about Fisherman's Friends. The true story is about a group of Cornish singing fisherman from Port Isaac in Cornwall, England who signed a £1 million record deal with Universal Records and saw their album of sea shanties debut at number nine in the British pop album charts, creating history as the first-ever folk album to reach such a position.

The Los Angeles Times reported on 6 July 2010 that Hollywood Studio, Columbia Pictures, had hired writers Piers Ashworth and Nick Moorcroft to write a script for the family adventure story Christian the lion.
