Opening the RSC's repertory season, Dominic Cooke treats John Marston's Jacobean political satire like a louche high-spirited comedy, rather than the dark misanthropic piece it has the potential to be. Setting it in a Latin American banana republic, it could easily be the plot of a Marx Brothers film. The hero, played by Anthony Sher, is a deranged dosser who is the republic's ousted ruler. In this hobo disguise, he chastises and badmouths-everyone at court until he regains his crown.
