49 Up is the seventh film in a series of landmark documentaries that began 42 years ago when UK-based Granada's World in Action team, inspired by the Jesuit maxim "Give me the child until he is seven and I will give you the man," interviewed a diverse group of seven-year-old children from all over England, asking them about their lives...

Filmed in IMAX, a team of explorers led by Pasquale Scaturro and Gordon Brown face seemingly insurmountable challenges as they make their way along all 3,260 miles of the world's longest and deadliest river to become the first in history to complete a full descent of the Blue Nile from source to sea.

After another 7 year wait, director Michael Apted revisits the same group of British-born children from Seven Up! and 7 Plus Seven. The subjects are interviewed as to the changes that have occurred in their lives during the last seven years.

Just two years away from turning 30, participants in Michael Apted's documentary series are facing serious questions of identity and purpose, wondering whether they've found their place in the world.
