Alexa joins Mulberry to launch Tim Walker film

The Lost Explorer is an adaptation of a Patrick McGrath book, which tracks the adventures of a young girl and an explorer found at the bottom of her garden- and its themes of adventure, nature and magic will resonate clearly with fans of Walker's distinctive dreamy aesthetic.

Following the screening of the twenty minute film, guests including Alexa Chung, Gemma Arterton, Amber Le Bon and Laura Bailey were in attendance at Claridges, where the ballroom had been transformed into an explorer themed wonderland, reached via a mosquito net strewn tent. Young newcomer Olympia Campbell, who stars in the film, was also present and demonstrating fashion credentials that belie her fourteen years.

Tim Walker has spoken frequently of his desire to start directing films, and The Lost Explorer is likely to be the first of many ventures into cinema for the prolific photographer. His next project is rumoured to be an adaptation of the gruseome Iain Banks novel The Wasp Factory; which will mark a dramatic departure from the environs of fashion editorial.
