Among Giants (1999)
Among Giants is a 1998 British film directed by Sam Miller, and written by Simon Beaufoy, fresh from his success with The Full Monty. It is set in Yorkshire, and stars Pete Postlethwaite, Rachel Griffiths and James Thornton. The plot came about after Beaufoy was refused permission to make a documentary on electricity pylon painters in Pembrokeshire, and converted the idea into fiction. The script predates that of The Full Monty, but only found a producer in the wake of the earlier film's success.
