David McVicar’s production of Dvořák’s Rusalka opens with a prelude while the overture plays. We see the Foreign Princess and the Prince. She appears to be upbraiding him and he is drinking hard. Are we seeing a failed/forced marriage that in reality the Prince made rather than some preferred alternative? Is what we see over the next three and half hours some dream version of what might have been? In this most Freudian of operas, why not?
