Stoppard’s m.o. is as a clever wordsmith, but it’s not just the vocabulary or even the ideas—it’s the rhythms.  They make his plays appealing to actors (for the movie version of R&G, Gary Oldman and Tim Roth kept exuberantly running scenes even after they’d been filmed) and especially appealing to read.  That’s fortunate, because Stoppard’s plays aren’t often available to see.
