1. The Lady Vanishes
I read some time last year that you could not consider yourself a serious film fan unless you had seen The Lady Vanishes. I'd read about it many times but had never seen it - at least no consciously. Fortunately a quick internet order remedied the deficiency: I really enjoyed it and it has an amazing vitality that belies its 1938 release date.
2. The Long Good Friday
I'd been a fan of Helen Mirren ever since O Lucky Man - I'd even watched her on Jackanory reading a story in an amazingly low cut Jacobethen dress - but this was the first time I'd seen her in a role that did justice to her talent. Bob Hoskins is pretty good too (understatement) and the whole film really caught the zeitgeist.
3. Casablanca
I'm not sure if this is a thriller or a lovely story, but who cares. It's a film I could see forever, and it was the film that my wife and I went to on our first date: a double bill with Play It Again Sam. We'll always have Casablanca.
4. Fargo
In our film society we try t show the best of releases, but several years ago we made an exception for Fargo - still one of the best films in a very strong field from the Coen brothers. since I'd first seen it I'd actually visited Minnesota several times for work and recognised the accent, but fortunately all my trips were in the Spring or the Autumn. And now I even have my own wood chipper.
5. Chinatown
I first saw this in my first year at university when I suddenly became aware of the big world of films that opened up around me. It's a brilliant homage to Hollywood of the 1940s as well as a key film of the 1970s - and several of the characters play key roles in David Thomson's brilliantly unsettling novel Suspects.
