The film has been acknowledged to draw extensively from the philosophy of Freud, Kristeva, Lacan and Jung, as well as Žižek. In particular, the portrayal of Grendel and his kin appeals to multiple forms of sexual unease, among them the castration anxiety, the monstrous feminine and the challenging of traditional gender roles. According to Nickolas Haydock, the film reflects the "American obsession with sex as the root of all evils," to the extent to compare Beowulf's and Hrothgar's portrayals to Bill Clinton and the history of sexual misconduct that caused his political decline. Nadine Farghaly also argues the story makes the point that unbridled desire only causes ruin.
