Half-demon (Vedhalam) concept in the film "Puli" was loosely based on Japanese anime manga series "Inuyasha" similar to which, Vijay is a "Tiger-demon" with tiger's teeth and blue eyes.
Vijay (Pulivendhan) and Sudeep's (Jalatharangan) characterizations had resemblances to on Snow and Stannis Baratheon. Costumes, armour and fighting skills in the film also have resemblances to "Game of Thrones".
