 The phrase "breaking the fourth wall" is used to describe such effects in those media.Instances of metatheatricality "other" than "breaking the fourth wall" occur in plays by many of the realist playwrights, including Henrik Ibsen, August Strindberg, and Anton Chekhov.As with modernism more generally, metareference in the form of metatheatricality comes to play a far more central and significant role in the modernist theatre, particularly in the work of Bertolt Brecht, Vsevolod Meyerhold, Luigi Pirandello, Thornton Wilder, Samuel Beckett, and many others.
