From ordinary to adventurous - Katrina Kaif will be donning different avatars in director Siddharth Anand's Bang Bang. She plays the character of Harleen, a bank receptionist, who is taken on a whirlwind time of her life. Be it displaying the simplicity of a girl-next-door or transforming into a sexy diva while romancing co-star Hrithik Roshan, or pulling off stunts as an action heroine, Kat has done it all.


says, "Harleen is a simple girl living her simple life before she gets embroiled in Rajveer's (Hrithik) life and ends up becoming the exact opposite of what she was. Harleen's journey is exciting and I hope everyone joins us on this roller coaster ride of fun, action and romance." Siddharth elaborates, "Rarely in an action film do the hero and heroine have equal parts. In that aspect, Bang Bang stands apart. So, it was important to cast someone who stands tall with Hrithik Roshan. And we found the perfect match in Katrina."
