In "Shaitan", Kirti played Tanya, an aspiring model, who gets no support from her family and, hence, has to struggle a lot.
"As compared to my role in 'Shaitan', it ('Rise Of The Zombies') was like a 'cakewalk'," the 28 year-old said here in an interview.
"I don't mean to sound anything else... just the fact that different characters have different characteristics," she added.
"Shaitan" was directed by Bejoy Nambiar, while Anurag Kashyap produced it.
Comparing her characters in both the films, Kirti said: In 'Shaitan', it was a very complicated character. Many things were going on in her life that were not allowing her to think normally and lead a normal life. In comparison to that, if you see Vinny's character, it is very sorted and balanced."
"She knows what she exactly wants in life. Her personal and professional life is all clear. So from that angle, it was very simple to play this character," added the actress, who managed to garner appreciation for her character of Tanya in "Shaitan".
"Rise Of The Zombies", which released Friday, features Luke Kenny as a wildlife photographer who then turns into a zombie. Besides acting in the film, Luke has co-directed the film with Devaki Singh.
