Ok... I accept the kicks to the pants.
It is NHITS!
:-) Thank you all who took the trouble to try to input data but encounted my thick skull.
I'm downloading it at the mo... free.. as a torrent.
The reason why I didn't think it was NHITS was:
A, it has US stars in it...
and:
B, the bits about exploring Canada looking in lakes!
It seemed the completely wrong film!!!
But allow me to acknowlege the power of the 'spotters gallery'! May your binoculars be ever bigger, but lighter!
