Many travel with theater groups or help in the training of other actors for larger roles. Actresses are required to memorize scripts, research characters and rehearse performances. They may be required to confer with others, including directors or other actors, to correctly display the right emotions, gestures and facial expressions. Acting is a highly competitive field and requires that actresses compete for roles through an audition process. Auditions are usually held with the casting director, director and/or producer. Auditions may require the actress to memorize lines or spend time researching ways to interpret the character.
