Exactly. Speaking of interchanging actors and parts, I read about a run in London of a play based on Frankenstein and Benedict Cumberbatch and Jonny Lee Miller are/were each in it. Moreover, each night, one plays the doctor, the other the monster and then they switch for the next night. I'd buy a DVD of this production (especially if they included one performance of each).
Oh, and I (as no doubt you) have no trouble enjoying both Sherlock and Elementary as two different, yet entertaining takes on the same characters, each of which is far removed from the original. Imagine if such an attitude could be prevalent among Trek fans. Oh wait--it is (well, for a lot of them, anyway).
That play sounds wonderful!
Unfortunately, now I'm going to spend the rest of the week imagining JLM in Sherlock
and Cumby in Elementary
