Maximum Overdrive. It has taken me until adulthood to get over the irrational fear that big machines like trucks will come alive and drive me over. For many, many years I always got a slightly uneasy feeling when I'm cycling and a big truck goes by (even though I live in a country with good bike infrastructure and bike on separated bike paths). Even now at 26 I occasionally get the feeling. It's silly, and I've mostly gotten over it. I guess my interest in cars and anything mechanical has helped me get over it, thankfully curiosity is sometimes strong than fear.
Funnily enough I occasionally listen to AC/DC and at some long ago point I stumbled upon their album "Who Made Who" and it became a favourite of mine. It was only a few years ago I realized that the album is the soundtrack to Maximum Overdrive!
Several years ago I actually bought a DVD copy of the movie; it's still wrapped in plastic to this day. It's not that I'm scared to see it, I just haven't gotten around to it yet, and by now I'm unsure where it even is any more.
