This was the only Season 1 episode to require cuts. Two shots were removed from the final film, both involving graphic depictions of oral sex. The first one occurred during the sex scene in the car, and the second occurred at the end of the film. The deleted scenes are edited into the 'So Hideous My Love' documentary on the DVD.
The asylum scenes were filmed on the same set as the ones in a previous episode, Dreams in the Witch-House (2005).
Jenifer contains an allusion to the film Frankenstein (1931); a little girl meets and talks with the titular monster as she throws flowers into the water.
