Continuity mistake: During the chase scene a man with a cap and a white suit leaves the baker's and gets chased for a while, during which his cap falls off. You can see the thread/string illuminated in the light which pulled the hat off.

Sir John Kierlaw: Now. Some fool has invented an indestructible cloth. Where is he? How much does he want?

Mrs. Watson, Sidney's landlady: Why can't you scientists leave things alone? What about my bit of washing when there's no washing to do?

Daphne Birnley, Alan Birnley's daughter: Thank you Sidney. If you would've said "yes" I could've strangled you.
