this is a great british black comedy in the vein of a fish called wanda, if you are not into quirky humour then try it still! i am 12 and I love this movie, it is a cleverly written and carefully planned comedy that will have you rolling with laughter! there is some brief nudity (rear male) and quite a lot of swearing (f word, sh word, w**ker etc.), some quite crude humour and drugs are used accidentally through out the film.
There are obvious references to two of the characters being gay, and it is implied that images of gay sex acts are shown to people at the funeral.
Not for the light hearted, but a good fun movie, one of my guilty pleasures, I think that a mature 12-13 year old would definitely enjoy it if they are clever enough to understand the subtle humour!!
