Sundance London cancelled for 2015

Launched in 2012 by Robert Redford, the festival aimed to promote smaller, independent films.

Last year's line-up, which featured Michael Fassbender's Frank Sidebottom comedy and Steve Coogan in The Trip To Italy, was said to be "the best yet".

At the time of writing, no reason had been given for the cancellation of 2015's event.

"We loved connecting with the vibrant community of filmmakers and audiences in the UK, and following a successful three years with The O2, we continue to explore our options for Sundance London," a spokesperson said in a statement to trade paper Screen Daily.

"Though we are not confirmed to host public events in London this year, we hope to be able to return very soon."

A spokesperson for The O2 added: "We loved having Sundance here and we'd be glad to have them back."

'New voices'

Initially launched as an experimental, four-day festival, the event was repeated in 2013 and 2014.

Speaking about the expansion in 2012, Redford praised the UK's "adventurous audiences".

"The vibrant arts community in London has informed this decision as much as anything," he added.

"Seeing what comes of nurturing a broader global community for new voices and varied perspectives in American independent film and music seems a worthy 21st century endeavour."
