Acting is the work of an actor or actress, which is a person in theatre, television, film, or any other storytelling medium who tells the story by portraying a character and, usually, speaking or singing the written text or play.

Most early sources in the West that examine the art of acting (Greek: ὑπόκρισις, hypokrisis) discuss it as part of rhetoric.

One of the first actors is believed to be an ancient Greek called Thespis of Icaria. An apocryphal story says that Thespis stepped out of the dithyrambic chorus and spoke to them as a separate character. Before Thespis, the chorus narrated (for example, "Dionysus did this, Dionysus said that"). When Thespis stepped out from the chorus, he spoke as if he was the character (for example, "I am Dionysus. I did this"). From Thespis' name derives the word thespian.

Acting requires a wide range of skills, including vocal projection, clarity of speech, physical expressivity, emotional facility, a well-developed imagination, and the ability to interpret drama. Acting also often demands an ability to employ dialects, accents and body language, improvisation, observation and emulation, mime, and stage combat. Many actors train at length in special programs or colleges to develop these skills, and today the vast majority of professional actors have undergone extensive training. Even though one actor may have years of training, they always strive for more lessons; the cinematic and theatrical world is always changing and because of this, the actor must stay as up to date as possible. Actors and actresses will often have many instructors and teachers for a full range of training involving, but not limited to, singing, scene-work, monologue techniques, audition techniques and partner work.

Kate Elizabeth Winslet (born 5 October 1975) is an English actress. She was the youngest person to accrue six Academy Award nominations, and won the Academy Award for Best Actress for The Reader (2008). She has won awards from the Screen Actors Guild, British Academy of Film and Television Arts, and the Hollywood Foreign Press Association among others, and has been nominated twice for an Emmy Award for television acting, winning once for her role as Mildred Pierce in the 2011 mini-series of the same name.

Brought up in Berkshire, Winslet studied drama from childhood, and began her career in British television in 1991. She made her film debut in Heavenly Creatures (1994), for which she received her first notable critical praise. She achieved recognition for her subsequent work in a supporting role in Sense and Sensibility (1995) and for her leading role in Titanic (1997), the highest grossing film at the time, and the highest grossing film of Winslet's career.

Since 2000, Winslet's performances have continued to draw positive comments from film critics, and she has been nominated for various awards for her work in such films as Quills (2000), Iris (2001), Eternal Sunshine of the Spotless Mind (2004), Finding Neverland (2004), Little Children (2006), The Reader (2008) and Revolutionary Road (2008). Her performance in the last of these prompted New York magazine critic David Edelstein to describe her as "the best English-speaking film actress of her generation". The romantic comedy The Holiday and the animated film Flushed Away (both 2006) are among the biggest commercial successes of her career.
