Cibber was the "de facto" leader of the triumvirate, and he led the theatre through a controversial but generally successful period until 1733, when he sold his controlling interest to John Highmore. It is likely that the sale was at a vastly inflated price and that Colley's goal was simply to get out of debts and make a profit (see Robert Lowe in his edition of Cibber's "Apology"). Members of the troupe at the time were most displeased; an actor's revolt was organised and executed; Charles Fleetwood came to control the theatre. Fleetwood's tenure was tumultuous; his abolition of the practice of allowing footmen free access to the upper gallery led to riots in 1737, and Fleetwood's gambling problems entangled the theatre in his own financial difficulties. It was during this period that actor Charles Macklin (a native of Inishowen in County Donegal in Ulster) rose to fame, propelled by a singular performance as Shylock in an early 1741 production of "The Merchant of Venice", in which he introduced a realistic, naturalistic style of acting, abandoning the artificial bombast typical to dramatic roles prior.
