Sundance London returns for two more years
Sundance London, which brought indie films and stars to Greenwich earlier this year, will return in 2013 and 2014.
Sundance president Robert Redford, who attended many events at The O2, had always said a repeat was down to the reception the export received.
Now he has announced his verdict - the debut had been "warmly welcomed by adventurous audiences".
He said: "The vibrant arts community in London has informed this decision as much as anything.
"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."
Alex Hill of AEG Europe, owners of The O2, said April's four-day showcase had been "hugely successful".
Visitors were able to see the best of the Utah festival including The Queen Of Versailles and Josh Radnor's Liberal Arts as well as attend panel discussions.
