‘Sherlock’ and ‘Game of Thrones’ stars join new medieval comedy movie

The movie adaptation of Catherine, Called Birdy has revealed its cast.

Based on Karen Cushman’s 1994 novel for children, the coming-of-age comedy is being adapted by Girls creator and star Lena Dunham.

Dunham first announced her plans for the project back in 2014, saying: “I’ve been obsessed with [the book] since I was a kid.”

The movie will follow the adventures of a teenage girl in Medieval England as she navigates through life and tries to avoid the arranged marriages her father maps out for her.

English actress Bella Ramsey will lead the cast as Catherine.

The 17-year-old is best known for her role as Lyanna Mormont in Game of Thrones.

Ramsey will be joined by Sherlock star Andrew Scott and Doctor Who star Billie Piper as the girl’s parents.

The book’s synopsis reads: “Catherine, a spirited and inquisitive young woman of good family, narrates in diary form the story of her fourteenth year – the year 1290.”

Catherine, Called Birdy will begin filming next month in the UK, with locations including Shropshire, Wales, and Gloucester.

The movie is expected to be released later this year.

Karen Cushman’s book is available on Amazon.
