Actress Vidya Balan, who earlier portrayed a sultry avatar of Silk Smitha in "The Dirty Picture", has returned with her same quirky side. This time as a sari-clad "bhabhi" in "Tumhari Sulu". The film has managed to win hearts and the good word-of-mouth is transforming into box office numbers as well. The Suresh Triveni directorial has been performing quite well at the box office with a collection of Rs 16.56 crore so far. Now the film is heading towards its second weekend. A few interesting moments in the film are the chemistry between Vidya and her onscreen husband Manav Kaul and the new version of "Hawa hawai"- a popular song, originally picturised on Sridevi in "Mr India".
