Prison life has inspired a rake load of quality drama down the years in both cinema and TV, but just how accurate are these depictions of life behind bars? Well, we can actually find out tonight as Channel 4 gives a countdown of celebrated prison movies, from dramas, thrillers and comedies, as voted for by convicts serving time in the UK. Yep, bizarre idea for a show 'ey? We won't lie though, we are pretty intrigued to know where the likes of Shawshank and The Great Escape fit in. As well as the countdown, it will also feature interviews with former inmates, those serving life, and great escapees, who provide their perspective on the plausibility of some of the cell-based hijinks devoured by cinema-goers over the ages.
