O2, the London concert venue, is in discussions with Sundance founder Robert Redford about staging a film festival. All O2 will say publicly is it would love to host a UK version of the Utah event. Negotiations are still at a very early stage, I’m informed. Redford told TV trade C21 website at Mipcom that a London festival would include documentaries, short films, indie features, and music. The O2 is a vast indoor arena in south-east London that used to be called the Millennium Dome. It includes a cinema, bars and restaurants and two concert halls, as well as the O2 Arena, where Michael Jackson was planning to stage his This Is It concerts.
