The Irvine Improv is doing a staged version of Star Trek featuring the episode Spock's Brain.
I suppose that if I had my way they would do this with every single episode of the original series. I noticed they are not doing it with the any of The Next Generation episodes. Which of course proves once and for all that the original series was far better TNG and that Jim Kirk was a better captain.
I bet that in a few years they'll start doing stage productions of the musical episode of Buffy.
