Actor Vinay Pathak, who has gained appreciable success with his offbeat films, is upset that his "Chalo Dilli" co-star Lara Dutta's potential has not been fully utilised by the industry.

"I am not a commercial celebrity. It's a fantastic opportunity for me to work with Lara. She is a fabulous actor, very underused in our industry. She has done some wonderful roles, but she is yet to be exploited, " Vinay told.

"I am ecstatic about that fact that we came together to work on a story and a film that has given ample opportunity to both of us to indulge in what we know the best, " he added.

But isn't it an odd pair on screen?

"It's a story of an odd couple that's why we have come together. The story requires such imagery and such characterisation, hence such actors, " said Vinay, who is working for the second time with director Shahant Shah after his critically acclaimed "Dasvidaniya".

Produced by Eros International in association with Big Daddy Production, "Chalo Dilli" is set to hit the theatres April 29.
