A TV series that has tracked the lives of a group of children at seven-year intervals over the past four decades, has been named the greatest documentary in a poll of filmmakers.
It beat such classics as the wildlife series Life On Earth, The World At War and Death On The Rock, about the SAS shooting of IRA suspects in Gibraltar.
But the presence of films by controversial American pundit Michael Moore in the Top Ten has annoyed some industry luminaries. Others are surprised by the good ratings of reality TV shows such as Faking It and Wife Swap.
A majority of 400 documentary makers and film experts agreed that Seven Up, the longest-running documentary in TV history, deserved to win.
