Going Postal airs today (30th)at 6pm on SKY1 with the second part airing tomorrow. The trailers certainly give the "movie" a different look and style compared to the previous two adaptations perhaps thanks in part to a new director.
This novel is one of my favourite Discworld stories despite not being a Guards or Witch based story but it has an excellent main character and the plot is very much grounded in real world events.
It's in HD as well, excellent:)
The Indianapolis 500 is on at the same time on SKY Sports, praise be the DVR.
