Oliver Parker and Barnaby Thompson's St Trinians has received $2.3m (£1.3m) National Lottery funding through the UK Film Council's Premiere Fund.
The film had faced an uncertain future having had its GAAP funding plans scuppered during last week's tax crackdown in the UK. It is one of very UK few films that had looked in significant difficulty after the move but now it can start shooting this weekend.
The cast includes Rupert Everett, Colin Firth, Stephen Fry, Jodie Whittaker, Tamsin Egerton, Tallulah Riley and comedian Russell Brand.
The film is being produced and directed by Oliver Parker and Barnaby Thompsonfrom a script written by Piers Ashworth and Nick Moorcroft.
'This is a British project through and through with a fantastic cast and a very experienced and talented production team. We are very pleased to be supporting St Trinian's, an exciting comedy feature with great potential to appeal to a contemporary audience.' said Sally Caplan, Head of the Premiere Fund.
The film is an Entertainment Film Distributors and Ealing Studios presentation of a Fragile Film with funding from the UK Film Council's Premiere Fund, Entertainment and Investec. Ealing Studios is handling international sales.
