On The Waterfront. It didn't exactly change my life as such, but it was a hugh eye opener for me. It was the first b+w film I ever saw when I was about 14. I'd loved films for many years up to that age, but being young I always went for the blockbusters of the day (that I could watch) or whatever looked fun to me. It was on TV and my dad had always said how good it was so I sat down and watched it. I was blown away by Brando's performance and I gained a new understanding of films, namely that oldies could definitely be goodies. After that I got my hand on many of the so-called b+w classics from the 50s and 60s such as Casablanca, Citizen Kane, King Kong etc.
