His comments, made in a forthcoming documentary to celebrate his career, will reignite the debate about how much classic literary works should be altered to fit modern attitudes.
Davies, 82, has changed female characters in several adaptations. In the BBC's 2005 version of Bleak House, critics noted that housekeeper Esther Summerson was more 'forceful and knowing' than originally depicted by Charles Dickens.
Three years later, his BBC adaptation of Little Dorrit focused more on the title character Amy Dorrit than Arthur Clennam, the older man who falls in love with her, as Dickens had.
In an interview at the time, Davies said: "It's called Little Dorrit. Let's try to put her at the centre." The 2016 BBC version of War & Peace included a controversial storyline of incest to enhance the role of Helene Kuragin played by Tuppence Middleton.
Jane Tranter, a former BBC executive who worked with Davies on several dramas, told the documentary: "Andrew will take those sort of pale-skinned, young, Dickensian virgin heroines and make them interesting. He will give them spirit."
Davies last night sought to play down his comments which he suggested had been made "half in jest". He added that any female characters he reinvented were an attempt to capture the zeitgeist, rather than to appease female TV bosses.
