Austen's novel mentions slavery on several occasions but does not elaborate on it. Most notably, in the novel, Fanny asks a question about the slave trade to Sir Thomas and is not answered. The film includes slavery as a central plot point, including explicit descriptions of the treatment of slaves (e.g. Fanny finds violent drawings of the treatment of slaves in Tom's room); numerous reminders of how Bertram family owes its wealth to slavery, as well as England's role in the slave trade.
