A rehearsal is a practice run for a sequence in a film or advertising production which serves the development of the footage which will ultimately be recorded.

Rehearsals take place in the preparation phase as well as during the shooting process, usually with the participation of the actors, although they are not limited only to them. Depending on necessity, technical processes or artistic processes can also be rehearsed. Even if a rehearsal only involves the preparation of a preliminary stage or a subsection of a production, it will always ultimately function as a means to support the optimal interpretation of the script from a directorial point of view.
