 It was soon leased by the prolific actor-manager George Coppin, who had already established himself as an actor at the Queen's Theatre, and would go on to build the Olympic (known as the "Iron Pot") on the corner of Exhibition and Lonsdale Streets - the future site of the Comedy Theatre, build the Haymarket Theatre and Apollo Music Hall, and lease (and eventually rebuild) the Theatre Royal in Bourke Street.In 1857, the amphitheatre was extensively renovated and the facade extended, re-opening as the Princess Theatre and Opera House.By 1885, the theatre came under the control of "The Triumvirate", a partnership between J. C. Williamson, George Musgrove and Arthur Garner.
