Mumbai, Nov 13 (IANS): Actress Ileana D'Cruz, who is working with Saif Ali Khan for the first time in "Happy Ending", says the actor is incredibly hard on himself.

The 27-year-old actress has so far worked with younger actors including Varun Dhawan and Ranbir Kapoor in Bollywood but working with 44-year-old Saif was a different experience.

"I don't get intimidated by anybody. For me, you are an actor and I'm just working with you. I want to do a film that offers me a significant role," she said.

"I was looking forward to working with Saif because the role demanded the humour and I think he is brilliant in that... He is incredibly hard on himself," she added.

Directed by Raj Nidimoru and Krishna DK, "Happy Ending" also features Govinda, Kalki Koechlin and Ranvir Shorey. The film will release Nov 21.

Ileana says that she was offered a film with Saif much before the release of her first Hindi film "Barfi!"

"For me, doing a film with Saif would be great but doing a film with Saif that has a significant role for me, has been the perfect combination. I was offered a film with Saif much before 'Barfi!' but I didn't like the story. When I heard the story of 'Happy Ending', I was shocked because this is an amazing script."

The actress says that her role in the film is as important as any other character.

"My role is very good, at par with him (Saif) and my character is as sassy as his. She is more of a guy than a girl. She is not emotional. My character is sort of dry and disinterested. She writes novels but doesn't believe in them, or for that matter in love," she added.
