The Italian Job (1969)

This is an absolute classic film and I see references to it all over the place. It has the classic line "you're only supposed to blow the bloody doors off" which loads of people will know and quote. Also it has one of the most famous endings from any film.
I am a huge fan of this original film, it is so retro and is just as cool now as I am sure it was when it was released. The main character, Charlie, is played wonderfully by Micheal Caine.
I love the way this film is shot and will continue to watch it for a long time to come.
