I saw Evil Dead in the store and it was 1:85:1. Originally Evil Dead was released 1:33:1 so it's been Masked for Widescreen. Although I think there were at least 1 release of ED on DVD at that ratio.
Anchor Bay's lastest dvd release of The Evil Dead was matted to 1.85:1 as per Sam Raimi's wishes. I personally feel that its a bit cramped looking in a few scenes but its still quite watchable.
