Western acting lore starts when Thespis left the chorus
Aristotle later claimed a sixth-century Athenian named Thespis stepped out of the dithyrambic chorus and spoke as a character—turning narration into enactment. From his name comes thespian, and from that split come centuries of argument over whether actors should feel or merely show.
Acting tells a story by having a performer adopt a character across theatre, film, television, radio, and other mimetic media. Skills range from imagination and emotional access to voice, physical clarity, dialects, improvisation, mime, and stage combat. Most professionals train for years in conservatories or colleges. Early Western writing often treated acting as rhetoric; Aristotle's Poetics from about 335 BCE contrasts mimesis—story through enactment—with diegesis—story through narration—when describing Thespis of Icaria addressing the chorus as Dionysus rather than recounting him.
North American schools often teach variants of Konstantin Stanislavski's system popularized as method acting by Lee Strasberg, Stella Adler, and Sanford Meisner. Other lineages stress body and image: Anne Bogart, Jacques Lecoq, Jerzy Grotowski, Vsevolod Meyerhold. Conservatories typically run two to four years of text, voice, and movement with heavy auditions. Improvisation shaped commedia dell'arte, Stanislavski's First Studio work after talks with Maxim Gorky in Capri, and later UK and US practice via Joan Littlewood, Keith Johnstone, Viola Spolin, and filmmaker Mike Leigh.
Stage fright elevates heart rate and blood pressure; a 2017 university study found experienced and novice actors alike showed high rates in performance, yet veterans had steadier variability. Semiotics asks how gesture, voice, and rhythm become signs for spectators who know screen performers are paid yet still accept the fiction. Theorists from Artaud to Brecht to Barba disagree whether actors should craft meaning, demonstrate social gestus, or leave signification to directors—echoing Diderot's old paradox of sincere feeling versus calculated distance.
