Moulineau (Philippe Noiret)'s dish specialty was the "pressed duck", Natasha O'Brien (Jacqueline Bisset)'s course specialty was "Le Bombe Richelieu" whilst Louis Kohner (Jean-Pierre Cassel)'s was "baked pigeon".
The film was made and released about two years after its source novel "Someone Is Killing the Great Chefs of Europe" by Nan Lyons and Ivan Lyons was first published in 1976. The film's source novelists later wrote another similarly titled book, "Someone Is Killing the Great Chefs of America".
Playing a pompous gourmet in this film was Robert Morley who due to the popularity of the character went onto make a series of successful television commercials for Heinz soup. Morley was awarded Best Supporting Actor from both the National Society of Film Critics Awards (1979) and the Los Angeles Film Critics Association Awards (1978). Morely was also nominated in the same category at the Golden Globes.
The picture was originally distributed by Warner Brothers but was produced by Lorimar. As such, the film was available on home video during the 1980s in territories which weren't Warner Bros. When Lorimar was bought by Warner Communications in 1989, they got the film back.
A line of dialogue in the film was "Too Many Cooks". The film's UK title was something like this. It was "Too Many Chefs" but wasn't called by the more common English expression which is "Too Many Cooks".

The gastronomic gruesome "grand guignol" gourmet murders are as follows: (1) Baked in an oven (2) Drowned in a lobster aquarium (3) Frozen in a meat fridge (4) Skull crushed in a duck press and the intended but unsuccessful (5) Blown-up with a bombe dessert.
The victims were chosen because of a feature in the fictional magazine in the film which had four chefs and their best dishes in a feature called "The World's Most Fabulous Meal". Jacqueline Bisset's character Natasha O'Brien is the only one of those four chefs not to be killed.
