I found that because i had read The Heart of Darkness by Joseph Conrad that Apocalypse Now was a much richer viewing. Some of those films are expensive to find, especially in the UK, however if you see them cheap, for rent or at a local movie theatre then i highly recommend viewing them. Luckily with ‘internet rental’, such as Blockbuster Lovefilm etc, it is easier to take a punt on a rare/odd/arty film without having to spend £20 on a film you may not like. In the coming weeks and months i will do an introduction, synopsis and review of these films.
