New Delhi, Feb 3 (IANS): Actress Parineeti Chopra is eagerly waiting to watch her elder sister Priyanka Chopra's forthcoming movie "Gunday" that will hit theatres Feb 14.

The 25-year-old, whose rom-com "Hasee Toh Phasee" will hit theatres Friday, says there is no competition with Priyanka.

While, this time their films have a gap of a week, in 2013, Parineeti's "Shuddh Desi Romance" and Priyanka's "Zanjeer" released on the same date, Sep 6.

"No, there is no competition with her (Priyanka). Infact I am just waiting to watch 'Gunday'. I just wish I get to see the movie at a screening before it releases on Feb 14," Parineeti told reporters during the promotion of her film here.

The actress will be seen essaying a mad scientist in the movie and she says portraying the character was "physically very exhausting" for her.

"The character that I am playing is very quirky. It is different from the ones I have played before. Usually in movies, either an actress plays a normal girl or a mentally challenged, but my character in the movie is between the two. It was physically very exhausting for me to play it," she said.

"The character is a bit off (mentally), she makes faces, she doesn't blink her eyes, she keeps her tongue out, so getting all that in a shot was very difficult. It was quite challenging for me," Parineeti added.

"Hasee Toh Phasee", which is directed by Vanil Mathew, also features Sidharth Malhotra in the lead role.
