My other favourite is in Mathieu Kassovitz's
The Crimson Rivers where Jean Reno as Commisaire Niemans is frightened by the blind child's dog. On the English dubbed version, the conversation with Jean Pierre Cassel's Dr Cherneze goes like this:
Cherneze: Who are you?
Niemans(rattled): Commisaire Niemans. Sorry, I'm scared of dogs.
If you listen in French with English subtitles, Jean Reno's actual reply is
Niemans: I apologize, dogs scare me sh-tless."
