Influence

Shakespeare's work has made a significant and lasting impression on later theatre and literature. In particular, he expanded the dramatic potential of characterisation, plot, language, and genre. Until Romeo and Juliet, for example, romance had not been viewed as a worthy topic for tragedy. Soliloquies had been used mainly to convey information about characters or events, but Shakespeare used them to explore characters' minds. His work heavily influenced later poetry. The Romantic poets attempted to revive Shakespearean verse drama, though with little success. Critic George Steiner described all English verse dramas from Coleridge to Tennyson as "feeble variations on Shakespearean themes." John Milton, considered by many to be the most important English poet after Shakespeare, wrote in tribute: "Thou in our wonder and astonishment/ Hast built thyself a live-long monument."

Shakespeare influenced novelists such as Thomas Hardy, William Faulkner, and Charles Dickens. The American novelist Herman Melville 's soliloquies owe much to Shakespeare; his Captain Ahab in Moby-Dick is a classic tragic hero, inspired by King Lear. Scholars have identified 20,000 pieces of music linked to Shakespeare's works, including Felix Mendelssohn 's overture and incidental music for A Midsummer Night's Dream and Sergei Prokofiev 's ballet Romeo and Juliet. His work has inspired several operas, among them Giuseppe Verdi 's Macbeth, Otello and Falstaff, whose critical standing compares with that of the source plays. Shakespeare has also inspired many painters, including the Romantics and the Pre-Raphaelites, while William Hogarth 's 1745 painting of actor David Garrick playing Richard III was decisive in establishing the genre of theatrical portraiture in Britain. The Swiss Romantic artist Henry Fuseli, a friend of William Blake, even translated Macbeth into German. The psychoanalyst Sigmund Freud drew on Shakespearean psychology, in particular, that of Hamlet, for his theories of human nature. Shakespeare has been a rich source for filmmakers; Akira Kurosawa adapted Macbeth and King Lear as Throne of Blood and Ran, respectively. Other examples of Shakespeare on film include Max Reinhardt 's A Midsummer Night's Dream, Laurence Olivier 's Hamlet and Al Pacino 's documentary Looking For Richard. Orson Welles, a lifelong lover of Shakespeare, directed and starred in Macbeth, Othello and Chimes at Midnight, in which he plays John Falstaff, which Welles himself called his best work.

In Shakespeare's day, English grammar, spelling, and pronunciation were less standardised than they are now, and his use of language helped shape modern English. Samuel Johnson quoted him more often than any other author in his A Dictionary of the English Language, the first serious work of its type. Expressions such as "with bated breath" (Merchant of Venice) and "a foregone conclusion" (Othello) have found their way into everyday English speech.

Shakespeare's influence extends far beyond his native England and the English language. His reception in Germany was particularly significant; as early as the 18th century Shakespeare was widely translated and popularised in Germany, and gradually became a "classic of the German Weimar era;" Christoph Martin Wieland was the first to produce complete translations of Shakespeare's plays in any language. Actor and theatre director Simon Callow writes, "this master, this titan, this genius, so profoundly British and so effortlessly universal, each different culture – German, Italian, Russian – was obliged to respond to the Shakespearean example; for the most part, they embraced it, and him, with joyous abandon, as the possibilities of language and character in action that he celebrated liberated writers across the continent. Some of the most deeply affecting productions of Shakespeare have been non-English, and non-European. He is that unique writer: he has something for everyone."

According to Guinness World Records, Shakespeare remains the world's best-selling playwright, with sales of his plays and poetry believed to have achieved in excess of four billion copies in the almost 400 years since his death. He is also the third most translated author in history.
