A list of the actor's names of the Duchess of Malfi's productions:

The double cast-list of Q1 indicates that the play was revived at least once, and possibly twice, between its first performance and publication in 1623' [Brennan].
List of actors who had played in the original production and in a revival, it was published in the Quarto of 1623. 'The Duchess of Malfi is the early English play to be published with a list of actors assigned to individual rôles; this innovation was not copied until 1629, in plays by courtier Carlell, and Massinger and Shirley.' [Brown]:

From the Quarto edition of 1678, 'As it is now acted at the Duke's Theatre' we know some of the actors' names. Brown said in his Introduction of The Duchess of Malfi, 'In 1662, Pepys judged the play 'well performed, but Betterton and Ianthe [Mary Saunderson, later Mrs Betterton] to admiration' and John Downes noted in Roscius Anglicanus: 'This Play was so exceeding Excellently Acted in all Parts; chiefly, Duke Ferdinand and Bosola: It fill'd the House 8 Days Successively, it proving one of the Best of Stock Tragedies.'
[From Brown, J.R., The Duchess of Malfi, The Revels Plays, Manchester University Press, 1981, p. lv-lvi]:

In 22 July 1707 the altered version The Unfortunate Dutchess of Malfy or the Unnatural Brothers was produced at the Queen's Theatre in the Haymarket. Cast and text were printed in the quarto of that year. 'The printed text (Q4) is not only cut itself, but contains printed indications of where further cuts were made in performance' [Brennan]:

'In the nineteenth century, The Duchess was usually performed in a version by R.H. Horne. He had made it as regular and respectable as possible; there is no Julia, and the duchess, now called Marina, is strangled off-stage.' [Brown] .
