It's easy to lose track of time in the middle of a three-hour musical drama. Les Misérables' Ramin Karimloo — who starred in the show's latest Broadway revival as Jean Valjean — learned that lesson the hard way. Or rather, his Cosette (Samantha Hill) did when her onstage father failed to appear for one of their more contentious scenes. Clearly the mistake didn't hurt his career, seeing as he's back on Broadway this season in Anastasia. But for at least a night, the superpower of telepathic apologizing would have really come in handy.
