As much as I believe that EVERYONE should see this show(fan of the movies or not) its hard for the people with the money to justify sending such a production across an ocean.
I would say if you can prove theres at least some demand for the show then they might consider it, so I would say email the producers(should be on
www.evildeadthemusical.com) and hope that they will take a chance on touring the show eventually.
As for a DVD, Ive talked to the writer of the show and he has told me that the DVD thing MIGHT take place eventually, but right now its not something that was stated in the contract, with Sam Raimi for the rights.
Id love to see a DVD too, but Id figure we are still at least a few years off that.
