accuracy in costuming, which would later become an inherent feature of realism in the 19th century. Macklin did not merely "study" the Jews. According to Appleton, "he actually interacted with them in marketplaces and learned to gradually adapt their way of speech". Finally, opening night came. This faithfulness to Shakespeare's original intent for the character, combined with Macklin's revolutionary method of attempting some semblance of realism in his performance, resulted in uproarious applause. Macklin himself confesses, "On my return to the green-room, after the play was over, it was crowded with nobility and critics, who all complimented me in the warmest and most unbounded manner". King George II saw the production and was so moved he could not fall asleep that night. "This is the Jew/ That Shakespeare drew" is a phrase attributed to Pope. Many tried to replicate Macklin's performance of Shylock, but none of the six actors that attempted the role at the rival Covent Garden theatre from 1744 to 1746 were able to match nearly the acclaim that Macklin had received for his Shylock. Even Macklin was unable to match his performance. He did have a varied career, filled with at least 490 roles, but none of them were anywhere near the uproar his Shylock caused. Even his two closest in hype, roles from The Confederacy and Love for Love, were roles designed to emulate Shylock. He played Shylock for nearly the next fifty years, as well as Iago in Othello and the Ghost in Hamlet. In Ben Jonson's Volpone, he played the part of Mosca. He was the creator of Sir Pertinax Macsycophant, a famous burlesque character, and he was Macbeth at Covent Garden in 1772, in a production with authentic Scottish costumes. Together with David Garrick, his student, friend, and partner, Macklin revolutionised acting in the 18th century. Garrick and Macklin eventually had a falling out in the mid-1740s, which derailed Macklin's rise whilst propelling Garrick's own career. Macklin, then the stage manager at Drury Lane, participated in an actor walkout. When the actors, led by Garrick, were forced to accept the owner's terms, they had to abandon Macklin, who, as the stage manager, could have quelled the actors' strike, rather than participated in it. Macklin felt betrayed by Garrick and the other actors and he refused the £3 a week that Garrick offered him. He also acted regularly in Dublin, in the Aunger Street
