6. THE EXORCIST
(William Friedkin, 1973)
One of the greatest horror films ever made, it continues to scare and fascinate viewers to this day. Film critic Mark Kermode stands by that it's the greatest film ever made and more and more film-makers reference it as a key influence on their work. You can now no longer look at a film that has anything to do with possession without thinking about this. It's been parodied, spoofed and ripped-off so many times, but it's still able to hold viewers from its enigmatic start to its harrowing ending.
(Steven Spielberg, 1975)
A favourite of many, it is one of the greatest films ever made. The direction, script, acting, editing - it all works. Its hellish production is almost as famous as the film itself, with Spielberg being driven insane from studio pressure and malfunctioning mechanical sharks. It kick-started the summer blockbuster but has yet to be equalled. A true cinematic masterpiece.
