Saw this the other day in Hollywood. It was made by the same folks that made the film. And it was awesome; the guys playing West and Hill were especially good.
"It can only be attributable to human error."
I also saw this in L.A. and it was EXCELLENT. The showing I had did have the understudy playing West but from what I hear from people who had been to the show a number of times he was actually better than the regular guy. I haven't seen the regular guy (cannot recall his name, sorry) but Brian Gillespie was freaking GREAT as Herbert West. Not to mention...kinda hot. :)
I highly recommend it as well. And sit in the "splash zone" for added fun.

Found this great interview with Stuart Gordon on the set of Re-Animator The Musical
