Fiennes cousins, actor and explorer, on the Nile

Squeezing through tiny tunnels into a mummy's tomb is not something to rattle veteran British explorer Ranulph Fiennes.

"I constantly felt I was in an Indiana Jones set. I keep (saying): 'Oh no, not snakes!'" actor Joseph Fiennes says of the scene in Fiennes Return to the Nile, a three-part documentary airing on the National Geographic channel this month.
