The poem for which Wilmot has been banished from court at the beginning of the film is "A Satyr on Charles II". The historical Wilmot really did submit that poem to the monarch accidentally, but he left court of his own accord, rather than at Charles' command.
Unlike most period films, this one was shot almost entirely with a hand-held camera. The two most notable shots with a fixed camera are the two panoramas of the interior of the theater, which was intentional.
The production spent £6,890 on vegetable oil-based smoke and fog, and £3,672 on 17th-century dildos.
Most of the film was lit using candles, rather than conventional movie lights. In order to keep the effect of candles, but still get enough light, cinematographer Alexander Melman designed a special piece of equipment, a stand that held a bank of candles and a reflective backing. These were known on the set as "birthday cakes".
