No specific plot details for Renfield have been revealed yet, other than it will reportedly be set in the present day rather than a period piece.
R.M. Renfield has previously been played by actors like Dwight Frye in 1931’s Dracula and Tom Waits in 1992’s Bram Stoker’s Dracula, but as the star of this particular story, Nicholas Hoult will have more room to deliver a more unique interpretation of the character.
So not only is it unclear if the movie will adapt any of the same beats from Bram Stoker’s Dracula, we don’t even know for sure how much of a presence the hotshot vampire will have in the tale.
