Dr. Acula is a vampire screenplay written by J.D., starring him as a vampire doctor. The title of the screenplay is formed by taking "Dracula", and separating "Dr" from it - forming "Dr. Acula".
Dr. Acula was first mentioned in "My Missed Perception", where the hospital picture doesn't come out, and the Janitor suggests that the hospital is full of vampire doctors. J.D then suspects that the Janitor knows about his screenplay, Dr. Acula. J.D. is very proud of his screenplay, especially after he is told by Dr. Cox that he has read it and did not hate it, although the screenplay is later burned by the Janitor using the sun and a magnifying glass. J.D. also attempts to make the film version of this, but there are problems after J.D. and and Turk argue over who should play 'Dr. Acula' and his assistant. The Janitor later steals the video camera used to film Dr. Acula, and uses it to catch Dr. Kelso vandalizing his van, possibly recording over some of the footage.
- Dr. Acula is referenced in the Zynga Game,Vampire Wars. It is named in an achievement named Calling Dr. Acula which the player gains by increasing his/her characters health to 3 separate levels.
- Mitch Hedberg, a comedian, used a joke involving a "Dr. Acula" in Mitch All Together, which was made in 2003. The first Episode that Dr. Acula appeared in was aired in 2006 ("My Missed Perception"), meaning the writers could have possibly been given the idea by Hedberg.
