Boucicault was about to produce one of his plays, "Led Astray," at the Union Square Theatre, New York, and selected Thorne to create the leading rôle. Taking him under his wing for a few months he succeeded in transforming the man. Under his able tutelage Thorne, discarding his ranting and mouthing methods, awoke the morning after the première of "Led Astray" to find himself famous. He became founder of the modern school of suppressed, natural acting and the most convincing actor of the American stage. He was not a man easily handled and had no respect for the rules and regulations of any theatre. He was in constant difficulties with A. M. Palmer, manager of the Union Square, but Palmer realized Thorne's value and put up with many annoyances from him. Thorne held despotic sway, much to the amusement of his companion players who loved him as they loathed the management. Palmer exercised every means within his power to humiliate Thorne, casting him for leading heavies for instance, but Thorne's convincing methods always made the hero look ridiculous. In the play "False Shame," in which he was cast for the villain, he took all the sympathy from the hero and of course killed the property. Palmer brought over the late Charles Coghlan at a salary of $1,000 a week--Thorne's salary had never gone beyond $125!--and cast them both to create simultaneously the leading rôle in "A Celebrated Case," giving Coghlan the quodus of the New York and Thorne the Pittsburgh opening. I saw Coghlan's opening. He gave a marvelously thought-out performance and made a tremendous hit. I saw Thorne some weeks after and told him of my impressions. I remarked, "Charlie, I think that Palmer has got you at last." He observed, "Yes, I hear that that chap Coghlan is an actor. I am up the spout as Palmer intends playing me at the Grand Opera House in two weeks and I guess the boys will get me as that English fellow has had the first whack at them and they will have the chance to compare us in the same rôle." I said, "Well, I am going in front to-night and I will tell you what I think." Before leaving his dressing-room I added, "Charlie, if you take my advice you won't go to New York. Be ill, and let your understudy go on." He laughed and, waving his hand, cried, "All right, sonny boy, I may take your advice!" I went in front and after the performance I rushed back into his dressing-room and yelled, "For God's sake, don't get ill! Get to New York as soon as possible!" I had never seen such a performance! While you admired Coghlan's technique and art, Thorne gave you no time to think of anything--he was so real, so convincing. He drowned all judgment with the tears his acting started. You simply sobbed your heart out.
