The film they used in the episode named 'Death Castle' is based on a rejected film script written by Nicolas Cage, who also played the imaginary lead role.
Dev (Aziz Ansari) only appears in the first and last shot, and has only 28 seconds of screen time, by far the least of any episode.
The voice of the male lead of the movie while it plays in the movie hall in the last scene is actually Andy Samberg pretending to be Nicolas Cage.
The episode is titled 'New York, I Love You' and follows the same format as the 2008 film of the same name.
When the taxi drivers are discussing their most famous passengers, one of the men makes a joke calling Arnold Schwarzenegger by the name of 'Eric Schwarzenegger' - this could be a subtle joke, relating Eric Wareheim to his character in the show of Arnold.
