The director, Anand Rai felt the title MANU WEDS TANU was appropriate and was even gung-ho about it. However, Kangna who plays the character of Tanu in the film insisted that the title should be TANU WEDS MANU and not MANU WEDS TANU as the tale and narrative unfolds from Tanu's point of view.
The director was highly flummoxed by this suggestion, he did not know how to handle it.
However, he was in for a surprise, when he approached Kangna for a reason, she had a very simple one. She felt that her character, Tanu which is a small town, wild girl, is the one in the commanding position throughout the film, and Madhavan's character Manu is shown as a simple, NRI boy. So TANU WEDS MANU shows Tanu as the one in the commanding position, and MANU WEDS TANU as the title seemed a little off.
Interestingly when the director tentatively spoke to Maddy, thinking he would be upset, Maddy readily agreed with Kangna and saw the point immediately.
Says director Anand Rai, "It's true that the film was earlier titled MANU WEDS TANU. However, we felt that TANU WEDS MANU was a more suitable title, according to the demands of the script. So we decided to go with TANU WEDS MANU."
Anand Rai immediately saw the reason in Kangna's suggestion, and decided to change the title to TANU WEDS MANU.
