Who is Killing the Great Chefs of Europe ?  was a crime-comedy-food movie that received mixed reviews.
I can only assume that the harsher ones came from vegetarians......there is rather a lot of meat and offal about, but in a nice way.
In the UK it was known as "Too Many Chefs". Love interest and stars Bisset and Segal were wonderfully hammed off the screen by Morley and the like.
This was Ronald Leigh-Hunts last movie - he of the Team Manager to Mike Delaney in "Le Mans".

This poster is great for La Bisset.
I also have other posters for this movie.....I even have the 1st. edition of the original novel by Nan and Ivan Lyons !
