This film is wonderful. I was given it for a Christmas present and it has been played regularly ever since.
As a dramatised history of Pirate Radio this is superb, the characters are all to various degrees, 'Mad,Bad,and dangerous to know,' but given the opportunity wouldnt you want to be part of that scene?
The sound track is brilliant, and offered up some lovely unknown tracks which added to the enjoyment.
Bill Nighy turns in a cracking performance and the Count was probably the best of a brilliant cast. Kenneth Branagh was suitably poisonous and must have enjoyed doing this role.
I also saw him in the role of Heydrich in the HBO film,Conspiracy, and comparing him in both films, Im not sure if he was nastier as the deputy commander of the SS in Conspiracy or as a Government minister in The Boat that rocked.
All in all well worth watching, but leave it just as it is, dont make a sequel as what would be the point, this has it all.
