How do you say directed by in french?

Here are some examples:

* "Le film a été réalisé par Quentin Tarantino." (The film was directed by Quentin Tarantino.)

* "Ce documentaire est réalisé par un jeune réalisateur." (This documentary is directed by a young filmmaker.)

You can also use "mis en scène par" which literally means "staged by," but it's less common than "réalisé par."
