Based on a book?
Okay, i caught this movie on bbc1 with 40 mins left to go, from it i picked up the following:
Toad causing hallucinations; teenagers and waterpistols.
Well, when i was younger i remember reading a book which was BLOODY FUNNY AS HECK! and upon watching the remaineder of this movie, i pissed myself in laughter. So i'm wondering, is this movie based on a book at all? If so, sweet, need to find the book again.
