Switchblade and James Dean
The first time I saw someone with a switchblade was James Dean in "Rebel Without a Cause". I often watched late night movies on school breaks at my grandma's house because my parents didn't let me stay up late.
My grandma always went to sleep early and she let me watch TV late at night. So I often watched movies alone. I'm not sure how old I was, but I was probably in middle school. It was great time for TV in Japan. Throughout the week, almost everyday, there were programs featuring movies from all over the world. Many of them were American movies.
