Project PP50: Francois

Dreyfuss' long suffereing assistant, Office François Duval (or is it Chevalier? Thee films say one, three the other) was a regular in the series played by Andre Maranne (until Son of the Pink Panther where he was played by Dermot Crowley. He doesn't appear in the new films, although there's a similar sort of character called Renard, but...meh.
