A screen test is a method of determining the suitability of an actor or actress for performing on film or in a particular role.  The performer is generally given a scene, or selected lines and actions, and instructed to perform in front of a camera to see if they are suitable.  The developed film is later evaluated by the relevant production personnel such as the casting director and the director.  The actor may be asked to bring a prepared monologue or alternatively, the actor may be given a script to read at sight ("cold reading").  In some cases, the actor may be asked to read a scene, in which another performer reads the lines of another character.
