Two more points about Rocky Horror, while I think of them:

I noticed last night that Rocky, the character, disappears somewhat in the final act. In the movie they get away with it when he grabs Frank and scales the tower, but on stage it seemed lop-sided. Oh well.

This is also an excuse to mention Summer of Secrets again. Not many people know that the director of the RHPS made a movie a year later in Australia, that is something of a thematic follow-up (not to be confused with Shock Treatment). Here is Kyla's review of the movie, for those who like tracking down such things.
