In the text of a Play or the Scenario of a Film, a didascalie is an indication of play or Mise in scene written by the author bound for the actors or of the director. It makes it possible to give information for example on the appropriate dress, a physical action or sometimes the mood of the character.

The didascalies thus do not form part of the dialog in oneself and are reproduced always in italic (sometimes between brackets) on the written text. They are comparable with the indications given in Italian by the type-setters of music since the 18th century.

It is also a note placed in bottom of the plays.

Didascale was the name given in ancient Greece to that which taught an art, in particular the dramatic art.
