Tom Stoppard's Rock N' Roll: "To Be Or Not To. . . Line!"

Last night, at the performance of Tom Stoppard's Rock 'N' Roll, Rufus Sewell went up on a line. (It's no wonder; there are so freakin' many of them.) After calling "Line!", Sewell asked the audience if they just should start the scene again, and they bravely ended up doing so. As a poster on All That Chat (on talkinbroadway.com) notes, maybe he was nervous because Al Pacino and Bruce Willis were in the audience. I'm sure the producers were nervous too, thinking, "We don't want to pay overtime. Just keep going!"
