 Angiers double mumbles a few lines from a speech while rehearsing  on stage before his first performance. What hes saying is actually  the words of Harry Percy (Hotspur) from Shakespeare (qv)s Henry  IV, when called to appear before the king and explain his failure to  turn over prisoners after a recent battle in Scotland. Apparently  Hugh Jackman (qv) has used this speech in previous auditions.  Presumably it was believed that having the double deliver a few  lines from Shakespeare would lend him an actorly air, as his  character is in fact a dissolute stage actor.
