* DuelingMovies: Possibly with the 2009 ''Film/MyBloodyValentine3D'', given how it came a month apart from each other and starred Creator/JensenAckles and Creator/JaredPadalecki, the two stars of ''Series/{{Supernatural}}''.
* HeyItsThatGuy:
** [[Series/{{Supernatural}} Sam Winchester]] and [[Series/TheMentalist Grace Van Pelt]] are the leads.
*** The former was possibly a nod to how Jason was going to cameo in an episode of ''Supernatural'', but was unable to due to [[ExecutiveMeddling the usual reason why awesome things are canceled.]]
** [[Film/{{Transformers}} Trent is here again, and he's still an asshole]].
* WhatCouldHaveBeen: The film was initially planned to be a prequel.
