The power of love in Kyun! Ho Gaya Naa...

What makes Kyun! Ho Gaya Naa... special? For one, it stars Vivek Oberoi and Aishwarya Rai together for the first time. The duo is reportedly seeing each other.

The film also features Amitabh Bachchan, who has had a flurry of releases hitting the marquee in 2004 -- Khakee, Aetbaar, Dev, Lakshya and Deewaar - Let's Bring Our Heroes Home.

Kyun! Ho Gaya Naa... marks the directorial debut of Sameer Karnik, who formerly assisted Vidhu Vinod Chopra on Kareeb.

As the title suggests, the film is an unlikely love story between a boy who is all for arranged marriages and a girl who is a diehard romantic.

"We

had a great time shooting the film," says Oberoi.

Ash's reason for signing on Kyun! Ho Gaya Naa... is simple. "I wanted to do comedy," she says. The actress, incidentally, began her career in Hindi films with a romantic comedy ...Aur Pyar Ho Gaya. Ash sports a curly hairdo in the film.

The soundtrack is composed by Shankar-Ehsaan-Loy and Javed Akhtar pens the lyrics.

The romantic tale is slated for an August 6 release.
