Harry Potter - Bonnie Wright Shows Off Directorial Debut At Cannes

The actress made Separate We Come, Separate We Go through her production company, Bon Bon Lumiere, and roped in acting pal David Thewlis - her co-star in the wizarding franchise - for the project.

Wright shot the movie on an $8,000 (£5,000) budget in Kent, south-east England as a graduate project for her degree at the London College of Communication - and the inspiration for the coastal film came from the star's childhood.

She tells Britain's Daily Telegraph, "It's a very unique area and an amazing stretch of land. Romney Marsh is an area where I spent a lot of time when I was a child. Growing up in a city such as London, it's so confined sometimes that as a child there is no feeling of a horizon, there's nothing beyond what you know.

"So for me I was so lucky to have that experience of spending a lot of time in open spaces such as Romney Marsh that I was able to gain that feeling of beyond. As a young child I was obsessed with horizons."
