There's at least one, two or many errors and mistakes in TV programmes and films. I know some to start... in Love/Hate, some of the scenes show Darren with his moustache and goatee beard but in the next scene it is completely shaved off. Then the scene after that, it's back again. And in The Shawshank Redemption where Andy talks to Red for the first time, some the prisoners in background wore khaki trousers and most others wearing dark trousers. Another one in the film is that when Brooks has been released on parole but didn't want to go, the prisoner doesn't need to have parole or even apply for it in reality, and can serve out the sentence at any time.
