(STAGED READING) The talented freaks of Brown Derby inflict their theatrical gifts on Alien, the literally gut-busting 1979 space-horror classic. Tonight the screenplay will be brought to life by a collection of beloved local hams including Nick Garrison, Imogen Love, Dusty Warren, and Rebecca Davis. Plus, stuffed animals and Silly String.
