I have to say I don't laugh when Herrmann shows up in the Hitchcock. There may be a chuckle a few shots earlier when, outside the Royal Albert Hall, his appearance is signalled in a poster advertising tonight's concert---I mean, "tonight's concert"---but, having seen the poster, we can hardly find anything either surprising or comedic about his appearance "on cue."
