What is the french translation of " tell no one"?

Question

This is the title of a book that was made into a french movie. I'm looking for the name of that movie.

Maybe "(Motus et) bouche cousue"?

A few French movies have the title "Bouche cousue" : http://www.imdb.com/find?s=tt&q=%22bouch...

And a few books : http://www.google.com/search?num=100&hl=...

Answer 2

ne dites personne

Answer 3

yup second answer is best!

Answer 4

Answer 5

Ne le dis (or ''dites'' if it's formal or you talk to several people) à personne.

EDIT: now I remember this movie. It's ''ne le dis à personne'' based on Harlan Coben's novel right?
