Last night I was drinking cappuccino with Britain's answer to Robert Redford in a Soho coffee bar. Elliot Grove and I go back a long way: we first met in 1993 when Grove launched Raindance, London's version of Sundance, the premier American independent film festival founded by Redford. Since then Sundance has increasingly been attacked for selling out to Hollywood. By contrast Raindance, now in its 17th year, is still going strong and retains an air of authentic independence.
