Time setting
The original crime happened in 1984, but the setting of this film...the cars, the house interior...you'd think it was the 50';s or 60's, but then you see the Tacoma Dome in the background, and that wasn't built until...uh...well it was completed in 1983. I remember when AC/DC set fire to it, there was a long period of reconstruction, and then the first act to play there again was AC/DC, and I think they nearly set fire to it again, so they banned pyrotechnics.
But the setting of the film is very hard to actually nail down.
