In Wallace and Gromit: the Curse of the Were-Rabbit (2005) the were-rabbit is a giant rabbit like Harvey. The local vegetable shop is named "Harvey's" in an affectionate nod to the film.

There is a slight similarity between Harvey and the cult black comedy Donnie Darko (2001). In the latter film, Jake Gyllenhaal plays a teenager who is plagued by the recurring appearance of a demonic 6 foot tall rabbit named Frank that only he can see and who warns him about the demise of the world in 28 days.
