Killigrew's investment in the new playhouse put the two companies on a level as far as technical resources were concerned, but the offerings at the Theatre Royal nevertheless continued to be dominated by actor-driven "talk" drama, contrasting with William Davenant's baroque spectacles and operas at Lincoln's Inn Fields. Internal power structures were the main reason for this difference: while Davenant skilfully commanded a docile young troupe, Killigrew's authority over his veteran actors was far from absolute. Experienced actors Michael Mohun (who Pepys called "the best actor in the world") and Charles Hart held out for shares and good contracts in the King's Company. Such a division of power between the patentee, Killigrew, and his chief actors led to frequent conflicts that hampered the Theatre Royal as a business venture. Nevertheless, it was mostly at the struggling Theatre Royal, rather than at the efficiently run Lincoln's Inn Fields, that the plays were acted that are classics today. This applies especially to the new form Restoration comedy, dominated in the 1660s by William Wycherley and the Theatre Royal's house dramatist John Dryden. Actors such as Hart and Charles II's mistress Nell Gwyn developed and refined the famous scenes of repartee, banter and flirtation in Dryden's and Wycherley's comedies. With the appearance of actresses for the first time at Drury Lane and Lincoln's Inn Fields in the 1660s, British playwrights wrote parts for outspoken female characters, daring love scenes and provocative breeches roles. In any case, the competition between the King's Company and the Duke's was good for the rebirth and development of English drama.
