Filmmaker Karan Johar feels the USP of his next production venture, "Ek Main Aur Ekk Tu", is the unusual pairing of Imran Khan and Kareena Kapoor.

"What's unusual is what's different and what's different is what is working today. So, I think Imran and Kareena being unusual is the USP of the film," the 39-year-old director-producer said at the 160th year celebration party of cosmetic brand "Kiehl's".
