I think Jeff and I watched Detour years ago, but it didn't make much of an impression on us. This time around, when I watched it as part of the Summer of Darkness, I watched it more closely.
Detour is the quintessential B picture noir, with a small budget and tight shooting schedule. Errol Morris said, "It has an unparalleled quality of despair, totally unrelieved by hope."
The movie includes these great lines:
"Life's like a ballgame. You got to take a swing at whatever comes along before you wake up and find it's the ninth inning."
I may be prejudiced because I am a baseball fan, but I think baseball expressions and metaphors are rich and beautiful.
