"I'm sad to say that if you have people of colour as the lead in a movie, it automatically becomes less commercial as far as financiers are concerned," says film director Gurinder Chadha.
The London-based director behind the 2002 hit Bend It Like Beckham says that as a result she struggles to attract funding for her new films.
Gurinder Chadha, who is British-Kenyan and of Indian origin, said she believed investors were "cautious" to back her work, which she said often explored the experiences of Asian communities and starred Asian actors.
Her new film Christmas Karma, inspired by Dickens' A Christmas Carol, features Big Bang Theory star Kunal Nayyar - who is a London-born Indian actor - as Scrooge.
