The Coast of Utopia, Tom Stoppard's critically acclaimed (and Tony-winning) three-play cycle about 19th century Russian radical philosophers, was, well, maybe one or two critically acclaimed plays too many, there's a sense of reassurance about Rock 'n' Roll. Stoppard's latest London hit to transfer to Broadway begins and ends in a gratifying one evening. It takes place in slightly more familiar times and places Cambridge, England, and Stoppard's native Czechoslovakia, from 1968 to 1990, when a rock-'n'-roll band comes to symbolize resistance to the Soviet-backed regime. And it doesn't require a reading list. Even better, the key figures in the London cast Rufus Sewell, above, Brian Cox and Sinead Cusack, as well as director Trevor Nunn are reprising their roles here. All of this means that come Nov. 4, Stoppard's intellectual theater games have a good chance of surviving the transatlantic voyage without the jet-lag feeling.
