One of the central props of “The Evil Dead” are its gallons and gallons of blood. Raimi has used so much blood in his films, that the Campbell star has repeatedly set records with best stage blood count. According to Campbell’s measure, blood needs clear Karo syrup, nondairy whipped cream backed to create a translucent, red food color, with a hint of blue to darken it into a good deep shade. According to Campbell, blood doesn’t taste good.
In “The Evil Dead”, blood is everywhere. It’s a pretty bloody movie. Since Karo syrup is so sticky, it covers everyone and everything. Raimi recalls having sticky hands, and having to wash herself often. The only problem is the lack of tap water. Raimi has to be creative – and endure extreme circumstances – just to get clean hands. He speak:
“There was no running water, and it was the 20s and 30s – we had no clothes to wear in the winter. It was freezing cold. When you stay in that cold for 16 hours, you start – I start to die. There’s no food and everything is covered in Karo syrup at that temperature So I’m running the camera, but my hands are covered in Karo syrup… The only water we have is in a hot water kettle so you can make instant coffee. Boil water in your hands from the faucet; that’s how you wash them, to load the film into the camera.”
Freezing room, boiling water, sticky, burning hands, all just to upload to cinematographer Tim Philo’s Arriflex16S camera. It seems that Raimi can endure the torture. Many others, he revealed, could not.
