Bertolt Brecht in the context of "Ernst Bloch"

A theatre practitioner is someone who creates theatrical performances and/or produces a theoretical discourse that informs their practical work. A theatre practitioner may be a director, dramatist, actor, designer or a combination of these traditionally separate roles. Theatre practice describes the collective work that various theatre practitioners do.

The term was not ordinarily applied to theatre-makers before the rise of modernism in the theatre. Instead, theatre praxis from Konstantin Stanislavski's development of his system is described through Vsevolod Meyerhold's biomechanics, Antonin Artaud's Theatre of cruelty, Bertolt Brecht's epic, and Jerzy Grotowski's poor theatre. Contemporary theatre practitioners include Augusto Boal with his Theatre of the Oppressed, Dario Fo's popular theatre, Eugenio Barba's theatre anthropology, and Anne Bogart's viewpoints.

A political drama can describe a play, film or TV program that has a political component, whether reflecting the author's political opinion, or describing a politician or series of political events.

Dramatists who have written political dramas include Aaron Sorkin, Robert Penn Warren, Sergei Eisenstein, Bertolt Brecht, Jean-Paul Sartre, Howard Brenton, Caryl Churchill, and Federico García Lorca.

Kurt Julian Weill (/waɪl/; German: [vaɪl]; March 2, 1900 – April 3, 1950) was a German-born American composer active from the 1920s in his native country, and in his later years in the United States. He was a leading composer for the stage who was best known for his fruitful collaborations with Bertolt Brecht. With Brecht, he developed productions such as his best-known work, The Threepenny Opera, which included the ballad "Mack the Knife". Weill held the ideal of writing music that served a socially useful purpose, Gebrauchsmusik. He also wrote several works for the concert hall and a number of works on Jewish themes. He became a United States citizen in 1943.

There have been many attempts at defining science fiction. This is a list of definitions that have been offered by authors, editors, critics and fans over the years since science fiction became a genre. Definitions of related terms such as "science fantasy", "speculative fiction", and "fabulation" are included where they are intended as definitions of aspects of science fiction or because they illuminate related definitions—see e.g. Robert Scholes's definitions of "fabulation" and "structural fabulation" below. Some definitions of sub-types of science fiction are included, too; for example see David Ketterer's definition of "philosophically-oriented science fiction". In addition, some definitions are included that define, for example, a science fiction story, rather than science fiction itself, since these also illuminate an underlying definition of science fiction.

The Encyclopedia of Science Fiction, edited by John Clute and Peter Nicholls, contains an extensive discussion of the problem of definition, under the heading "Definitions of SF". The authors regard Darko Suvin's definition as having been most useful in catalysing academic debate, though they consider disagreements to be inevitable as science fiction is not homogeneous. Suvin's cited definition, dating from 1972, is: "a literary genre whose necessary and sufficient conditions are the presence and interaction of estrangement and cognition, and whose main formal device is an imaginative framework alternative to the author's empirical environment". The authors of the Encyclopedia article—Brian Stableford, Clute, and Nicholls—explain that, by "cognition", Suvin refers to the seeking of rational understanding, while his concept of estrangement is similar to the idea of alienation developed by Bertolt Brecht, that is, a means of making the subject matter recognizable while also seeming unfamiliar.

Epic theatre (German: episches Theater) is a theatrical movement that arose in the early to mid-20th century from the theories and practice of a number of theatre practitioners who responded to the political climate of the time through the creation of new political dramas. Epic theatre is not meant to refer to the scale or the scope of the work, but rather to the form that it takes. Epic theatre emphasizes the audience's perspective and reaction to the piece through a variety of techniques that deliberately cause them to individually engage in a different way. The purpose of epic theatre is not to encourage an audience to suspend their disbelief, but rather to force them to see their world as it is.

Captain Macheath is a fictional character who appears both in John Gay's The Beggar's Opera (1728), its sequel Polly (1777), and 150 years later in Bertolt Brecht's The Threepenny Opera (1928).

John Heartfield (born Helmut Herzfeld; 19 June 1891 – 26 April 1968) was a German visual artist who pioneered the use of art as a political weapon. Some of his most famous photomontages were anti-Nazi and anti-fascist statements. Heartfield also created book jackets for book authors, such as Upton Sinclair, as well as stage sets for contemporary playwrights, such as Bertolt Brecht and Erwin Piscator.

The Threepenny Opera (Die Dreigroschenoper [diː dʁaɪˈɡʁɔʃn̩ˌʔoːpɐ]) is a 1928 German "play with music" by Bertolt Brecht, adapted from a translation by Elisabeth Hauptmann of John Gay's 18th-century English ballad opera, The Beggar's Opera, and four ballads by François Villon, with music by Kurt Weill. Although there is debate as to how much contribution Hauptmann might have made to the libretto, Brecht is usually listed as sole author and Hauptmann as the sole translator, which was probably an unfair oversimplification typical of the time.

The work offers a socialist critique of the capitalist world. It opened on 31 August 1928 at Berlin's Theater am Schiffbauerdamm.
