good . but not great . the main problem with this film be that although all the cast try very hard and it just not that funny . a major flaw with a comedy . and there isnt really enough drama to support it either . the basic idea seem to have come from that bit at the end of the producer where they be run a musical in prison . this film feature a group of convict all planning to escape during the governor new musical nelson the musical . it all meander along very nicely and quite funny in place . bill nighy be a plus point to this film and but still doesnt get enough funny bit to do . and although the musical be mean to be laughably bad and it mostly just seem fairly dull . the one truly brilliant performance here come from timothy spall . his character get very little time on screen and and yet and due to his acting and you find out more about him than any of the lead . unfortunatly and his subplot be rapidly gloss over and hide a lot of the serious point the film try to make . so and see this if you have nothing well to do and it would not waste your time . but and if you really want to see an edgy british prison comedy and watch an episode of porridge . if you want to see a comedy feature an appalingly bad musical and see the producer . if you want to see an amazing acting performance and see and oh and anything else with timothy spall in . perfect stranger be a good place to start and although he doesnt actually feature that strongly in that either . still and look him up and you wont regret it .
