Director Greta Gerwig has admitted that she has "no feelings left" after completing her critically-acclaimed version of Little Women.

She told Elle UK that she cried both while writing and making the coming-of-age period drama based on the book by Louisa May Alcott, adding: "Little Women feels as personal as anything I'll ever make."

The movie is the eighth feature film adaptation of the classic 1868 novel, which follows the four feisty March sisters - Meg, Jo, Amy and Beth.

Gerwig also told Elle that when she is working on films she goes "into a zone where I don't wash or return calls and I go feral". She added: "I can go into hyperfocus as well as becoming more scattered.

"I like things that have a great deal of pressure and a lot of deadlines, because I need it."

Little Women's all-star cast included Saoirse Ronan, Timothee Chalamet, Emma Watson, Laura Dern, Florence Pugh and Meryl Streep.

Gerwig added that she was "terrified" to work with the legendary Streep, who played Aunt March in the film.

"She's so smart and she knows more about how films are made than anyone," said Gerwig.

"There were a couple of lines I wrote to get a character from A to B, inelegantly, and you know when Meryl asks, 'now why do I say that?' you'd better have a ****ing good answer.

"It's intimidating, but it forces you to be better. Unfortunately, it's uncomfortable to get better, because it means you have to look like an idiot in front of her. But she's fabulous."
