The English term of script doctor indicates, in the medium of audio-visual, a person with whom it is appealed to intervene on a Scénario in order to improve it and to make it exploitable.

It is generally about an experienced scenario writer himself. Jean-Claude Carrière thus often operated for this reason, but the actress Carrie Fisher (the Leia princess of Star Wars ) also had a name on the matter with Hollywood.

Other script doctors famous: William Goldman, Ben Hecht, Yves Lavandier, Claude Sautet, Linda Seger, Francis Veber.
