Katrina Kaif is gung-ho about Nitya Mehra's time travel adventure,Kal Jisna Dekha,which she promises is a love story you don't expect, reports Mumbai Mirror. When asked to define love, Katrina said, "Love is complex. I recently watched the animated feature,Inside Out,which deals with six emotions with 25 men between ages 25-35 and I've never felt so much emotion amongst guys. Life is a journey of highs and lows, understanding what makes you happy and what works for you. Love is an important aspect."
