For female stars, this included lessons in posture and diction as well as acting. Actresses were often put on diets as well as certain surgical procedures to meet the physical requirements expected by the studio. The final touch was the glamorization process of hair, makeup and wardrobe. Actors portray characters in stories such as plays, musicals, films, television shows and radio shows. They engage with the audience and convince them through altered speech patterns, hand gestures and more that they truly are the character. When necessary, actors also change their appearance such as their hair color or body weight to physically portray and embody their character.
