Renfield sees Nicolas Cage play Dracula.

In filmmaker Chris McKay's horror-comedy, R. M. Renfield, Dracula's patient, insect-eating servant, 

Is given more prominence, with Nicolas Cage's portrayal of the fabled vampire serving as the film's trump card.

The end product is a crazy concoction of fast-paced action, cartoonish gore, and humor that restrain

Cage's customary outrageous grandstanding and casts him in a supporting position where less is ultimately more.

Nicholas Hoult's Renfield (Nicholas Hoult) and Dracula are holed up in an abandoned New Orleans hospital where 

the latter is recovering from an encounter with vampire hunters that has left him overcooked. 

The film opens with a wonderful black and white recreation of the 1931 classic Dracula to introduce the characters.

Renfield joins a support group for those caught in unhealthy relationships and makes the decision to help his fellow group members,

By giving their abusive partners to Dracula in an effort to help them escape the clutches of his undead master and start a new life.
