Moorcroft was born in Chelmsford, Essex, in 1978. In an interview with Dalya Alberge, a journalist from The Observer, he revealed he was expelled from school when he was fourteen. He was subsequently home-schooled by the local council until he was accepted by Rainsford School, which was later placed in special measures and closed down by the government. He left school with no qualifications and was frequently in trouble with the police. His mother encouraged him to audition for the Webber Douglas Academy of Dramatic Art where he won a scholarship to study at the prestigious drama school before embarking on a career as a screenwriter and film producer.
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 #2 in the UK just behind Avatar with debut week end box office figures of £1,586,832. 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 are 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, has hired writers Piers Ashworth and Nick Moorcroft, to write a script for the family adventure story Christian the lion.
The true story about John Rendall and Ace Bourke who bought a lion cub at Harrods department store in 1969, became an internet sensation in 2008 when a heart warming clip appeared on YouTube of Christian the lion recognizing his former owners in the wilds of Africa after they had raised it as their own in their London flat on the Kings Road then arranged for him to be returned to Kenya and reintroduced into the wild by George Adamson. The clip has been viewed more than 14 million times. The adventure story will be produced by Hollywood mega-producer Neal Moritz who is behind the films The Fast and the Furious and I Am Legend.
